More and more researchers engage into investigation of electromagnetic applications, especially these connected with mechatronics, information technologies, medicine, biology and material sciences. It is readily seen when looking at the content of the book that computational techniques, which were under development during the last three decades and are still being developed, serve as good tools for discovering new electromagnetic phenomena. It means that the field of computational electromagnetics belongs to an application area rather than to a research area. This publication aims at joining theory and practice, thus the majority of papers are deeply rooted in engineering problems, being simultaneously of high theoretical level. The editors hope to touch the heart of the matter in electromagnetism. The book focuses on the following issues: Computational Electromagnetics; Electromagnetic Engineering; Coupled Field and Special Applications; Micro- and Special Devices; Bioelectromagnetics and Electromagnetic Hazard; and Magnetic Material Modelling.

Stuart Wolf This book originated as a series of lectures that were given as part of a Summer School on Spintronics in the end of August, 1998 at Lake Tahoe, Nevada. It has taken some time to get these lectures in a form suitable for this book and so the process has been an iterative one to provide current information on the topics that are covered. There are some topics that have developed in the intervening years and we have tried to at least alert the readers to them in the Introduction where a rather complete set of references is provided to the current state of the art. The field of magnetism, once thought to be dead or dying, has seen a remarkable rebirth in the last decade and promises to get even more important as we enter the new millennium. This rebirth is due to some very new insight into how the spin degree of freedom of both electrons and nucleons can play a role in a new type of electronics that utilizes the spin in addition to or in place of the charge. For this new field to mature and prosper, it is important that students and postdoctoral fellows have access to the appropriate literature that can give them a sound basis in the funda mentals of this new field and I hope that this book is a very good start in this direction."

This monograph contributes to the mathematical analysis of systems exhibiting hysteresis effects and phase transitions. Its main part begins with a detailed study of models for scalar rate independent hysteresis in the form of hysteresis operators. Applications to ferromagnetism, elastoplasticity and fatigue analysis are presented, and two representative distributed systems with hysteresis operator are discussed. The attention then shifts to the mechanisms of energy dissipation and transformation that induce a hysteretic behavior in continuous media undergoing phase transitions. After an introduction to phenomenological thermodynamic theories of phase transitions, in particular, the Landau-Ginzburg theory and phase field models, several specific models are discussed in detail. These include Falk's model for the hysteresis in shape memory alloys and the phase field models due to Caginalp and Penrose-Fife. The latter are studied both for conserved and non-conserved order parameters. A chapter presenting a mathematical model for the austenite-pearlite and austenite-martensite phase transitions in eutectoid carbon steels concludes the book.

In this text, Shigeji Fujita and Salvador Godoy guide first and second-year graduate students through the essential aspects of superconductivity. The authors open with five preparatory chapters thoroughly reviewing a number of advanced physical concepts-such as free-electron model of a metal, theory of lattice vibrations, and Bloch electrons. The remaining chapters deal with the theory of superconductivity-describing the basic properties of type I, type II compound, and high-Tc superconductors as well as treating quasi-particles using Heisenberg's equation of motion. The book includes step-by-step derivations of mathematical formulas, sample problems, and illustrations.

This book considers problems of optimization arising in the design of electromagnetic radiators and receivers. The authors develop a systematic general theory that can be applied to a wide class of structures. The theory is illustrated with familiar, simple examples and indications of how the results can be applied to more complicated structures. The final chapter introduces techniques from multicriteria optimization in antenna design. The material is intended for a dual audience of mathematicians and mathematically-sophisticated engineers. References to both the mathematics and engineering literature help guide the reader through the necessary mathematical background.

Computational and Instrumental Methods in EPR is devoted to both instrumentation and computation aspects of EPR, while addressing applications such as spin relaxation time measurements. However, this is the first comprehensive volume to offer practical, non-invasive spectroscopic methods of analyzing the rheology of biopolymers: comparative studies of polymer fluidity using traditional methods (e.g. viscosity) and nuclear magnetic resonance.

Nikola Tesla was one of the 20th century's great pioneers; his role in advancing electrical energy through the use of alternating current, and his stupendous engineering finesse, make this biography by journalist John J. O'Neill a fine read. Born in a Serbian village to a religious family, Nikola demonstrated an early interest in physics. The nascent science behind electricity - in the 1870s a mysterious, unharnessed force - became his passion. Though the young man's engineering aspirations were almost derailed when he contracted cholera, and later by Austro-Hungarian conscription, Tesla managed to enrol to study in Graz, Austria. A top-class student, tutors admiration for Tesla's gifts and boundless curiosity was tempered by concerns over his tendency to overwork. These attributes marked Tesla's professional life; an obsessively driven man, Tesla's gifts for invention were amply demonstrated and rewarded in the United States. As his ambitions grew in size and scope, Tesla was hailed as a visionary.

Electromagnetic transient phenomena in transformers and rotating machines are complicated by their winding structures, with transient phenomena caused by either external events such as lightning, or by internal events such as switching operations and faults. Electromagnetic Transients in Transformer and Rotating Machine Windings explores relevant theoretical frameworks, the latest empirical research findings, and industry-approved techniques in this area. Written for professionals who want to improve their understanding of the electromagnetic transient phenomena in transformer and rotating machines windings, this research volume is also useful for university research students in power system protection, insulation condition monitoring, and incipient fault diagnosis.

Paleomagnetic data are useful in many applications in Earth Science from determining paleocurrent directions to analyzing the long-term behavior of the geomagnetic field.

In this book, an attempt has been made to draw together the various principles and practices within paleomagnetism in a consistent and up-to-date manner. It includes many practical examples that illustrate various applications of paleomagnetism. A companion software package implements the theory explained in the text.

Audience: This volume is aimed at professional Earth Scientists using paleomagnetic data for their research. It is also suitable for use as a text book for students in courses with a paleomagnetic content. In addition, this volume will be of value to other professionals with an interest in the analysis of vector and tensor data in general.

The unexpected and therefore really amazing discovery of J.G. Bednorz and K.A. MA1/4ller, that certain oxide compounds enter a superconductivity state at temperatures above 30 K, pushed research on superconductivity into the limelight of science in general in a way that seemed reserved only for high energy or particle physics. It may therefore be expected that this entire review would solely deal with superconductivity at high temperatures, i.e. above the boiling point of hydrogen. Any unexpected occurrence of superconductivity is, however, a challenge to scientists interested either in the physics of this phenomenon or in its materials science aspects. In this respect, the eighties have been quite revolutionary in the sense that, on various occasions, superconductivity was discovered in materials whose physical properties were not obviously favourable for adopting this ground state. Therefore, apart from emphasizing the topic of oxide superconductors, this collection of reprints also contains a selection of papers that deal with other subjects, such as coexistence of magnetic order and superconductivity, heavy electron and organic superconductors. This is all the more justified when we consider the fact that various aspects of superconductivity in high Tc oxide compounds are, or might be, connected with features that are also observed in these other materials. For nonspecialists who might be interested in this collection of reprints the Editor briefly reviews the possibilities for identifying superconductivity and discusses some special features of the superconducting state.

As Charlton Heston put it: 'There's a temptingly simple definition of the epic film: it's the easiest kind of picture to make badly.' This book goes beyond that definition to show how the film epic has taken up one of the most ancient art-forms and propelled it into the modern world, covered in twentieth-century ambitions, anxieties, hopes and fantasies. This survey of historical epic films dealing with periods up to the end of the Dark Ages looks at epic form and discusses the films by historical period, showing how the cinema reworks history for the changing needs of its audience, much as the ancient mythographers did. The form's main aim has always been to entertain, and Derek Elley reminds us of the glee with which many epic films have worn their label, and of the sheer fun of the genre. He shows the many levels on which these films can work, from the most popular to the specialist, each providing a considerable source of enjoyment. For instance, spectacle, the genre's most characteristic trademark, is merely the cinema's own transformation of the literary epic's taste for the grandiose. Dramatically it can serve many purposes: as a resolution of personal tensions (the chariot race in Ben-Hur), of monotheism vs idolatry (Solomon and Sheba), or of the triumph of a religious code (The Ten Commandments). Although to many people Epic equals Hollywood, throughout the book Elley stresses debt to the Italian epics, which often explored areas of history with which Hollywood could never have found sympathy.

Starting in 1995 numerical modeling of the Earth's dynamo has ourished with remarkable success. Direct numerical simulation of convection-driven MHD- ow in a rotating spherical shell show magnetic elds that resemble the geomagnetic eld in many respects: they are dominated by the axial dipole of approximately the right strength, they show spatial power spectra similar to that of Earth, and the magnetic eld morphology and the temporal var- tion of the eld resembles that of the geomagnetic eld (Christensen and Wicht 2007). Some models show stochastic dipole reversals whose details agree with what has been inferred from paleomagnetic data (Glatzmaier and Roberts 1995; Kutzner and Christensen 2002; Wicht 2005). While these models represent direct numerical simulations of the fundamental MHD equations without parameterized induction effects, they do not match actual pla- tary conditions in a number of respects. Speci cally, they rotate too slowly, are much less turbulent, and use a viscosity and thermal diffusivity that is far too large in comparison to magnetic diffusivity. Because of these discrepancies, the success of geodynamo models may seem surprising. In order to better understand the extent to which the models are applicable to planetary dynamos, scaling laws that relate basic properties of the dynamo to the fundamental control parameters play an important role. In recent years rst attempts have been made to derive such scaling laws from a set of numerical simulations that span the accessible parameter space (Christensen and Tilgner 2004; Christensen and Aubert 2006).

This book appears at a time of intense activity in optical phase conjugation. We chose not to await the maturation of the field, but instead to provide this material in time to be useful in its development. We have tried very hard to elucidate and interrelate the various nonlinear phenomena which can be used for optical phase conjugation.

This book offers a balanced and comprehensive guide to the core principles, fundamental properties, experimental approaches, and state-of-the-art applications of two major groups of emerging non-volatile memory technologies, i.e. spintronics-based devices as well as resistive switching devices, also known as Resistive Random Access Memory (RRAM). The first section presents different types of spintronic-based devices, i.e. magnetic tunnel junction (MTJ), domain wall, and skyrmion memory devices. This section describes how their developments have led to various promising applications, such as microwave oscillators, detectors, magnetic logic, and neuromorphic engineered systems. In the second half of the book, the underlying device physics supported by different experimental observations and modelling of RRAM devices are presented with memory array level implementation. An insight into RRAM desired properties as synaptic element in neuromorphic computing platforms from material and algorithms viewpoint is also discussed with specific example in automatic sound classification framework.

This book serves as an introduction to magnetohydrodynamics (MHD) for graduate and advanced undergraduate engineering students. It may be used by engineers and physicists in research institutions and industry to become familiar with the particular phenomena of magnetothermohydraulics in technical liquid metal flows influenced by magnetic fields. The starting point of the book is the outcome of a recent nuclear fusion project. Therefore, it contains many new results that can be utilized for the design and optimization of various technical systems and processes.

The book aims to present current knowledge concerning the propagation of electro magnetic waves in a homogeneous magnetoplasma for which temperature effects are unimportant. It places roughly equal emphasis on the radio and the . hydromagnetic parts of the electromagnetic spectrum. The dispersion properties of a magnetoplasma are treated as a function both of wave frequency (assumed real) and of ionization density. However, there is little discussion of propagation in a stratified medium, for of collisions is included only which reference may be made to Budden 1] . The effect in so far as this can be done with simplicity. The book describes how pulses are radiated from both small and large antennas embedded in a homogeneous magneto plasma. The power density radiated from a type of dipole antenna is studied as a function of direction of radiation in all bands of wave frequency. Input reactance is not treated, but the dependence of radiation resistance on wave frequency is described for the entire electromagnetic spectrum. Also described is the relation between beaming and guidance for Alfven waves."

Gaseous Dielectrics VIII covers recent advances and developments in a wide range of basic, applied, and industrial areas of gaseous dielectrics.

Earth 's magnetic field is currently changing dramatically. Is the observed decrease of the dipole moment indicating a future polarity transition? What would be the effects of such a drastic change on system Earth? Can any positive or negative effects on our biosphere or even humans be expected?

This book gives a first overview about the geomagnetic field in general and serves as an introduction into geomagnetism. As the topic of the book covers a wide range of scientific disciplines, the first chapter summarises basic principles of geomagnetism and related fields including a historic overview, instruments and measurements, paleomagnetic fields, basics of dynamo theory, etc. The contributed chapters review major results of international activities aiming at understanding the causes and effects of geomagnetic field variations in view of the questions above.

The part Fundamentals is novel, first in that it stresses the use of electric currents in Magneto-Fluid-Dynamics. As a rule, authors discuss magnetic field lines without ever referring to the required electric currents. Second, the book stresses the importance of electric space charges inside conductors that move in magnetic fields. It is the custom to disregard both the required electric currents and the field of the space charges; this leads to many absurd results. The Case Studies concern solar phenomena and the Earth's magnetic field, stressing electric currents and electric space charges. Each case study is based on a published, or soon to be published, paper.

Turbulence and magnetic fields are ubiquitous in the Universe. Their importance to astronomy cannot be overestimated. The theoretical advancements in magnetohydrodynamic (MHD) turbulence achieved during the past two decades have significantly influenced many fields of astronomy. This book provides predictive theories of the magnetic field generation by turbulence and the dissipation of MHD turbulence. These fundamental non-linear problems were believed to be tractable only numerically. This book provides complete analytical descriptions in quantitative agreement with existing numerics, as well as theoretical predictions in physical regimes still unreachable by simulations, and explanations of various related observations. It also discusses and promotes the astrophysical applications of MHD turbulence theories, including (i) the particle acceleration and radiation in high-energy phenomena, e.g., Gamma-Ray Bursts, supernova remnants, cosmic rays; (ii) interstellar density fluctuations and the effect on observations, e.g., Faraday rotation, scattering measurements of Galactic and extragalactic radio sources; (iii) density and magnetic field structure in molecular clouds toward star formation. In closing, this book demonstrates the key role of MHD turbulence in connecting diverse astrophysical processes and unraveling long-standing astrophysical problems, as foreseen by Chandrasekhar, a founder of modern astrophysics.

This book is a glimpse into the works and ideas that were discussed and presented at the conference. It includes works on diverse fields from nanomaterials to fuel cells, photocatalysis to ferromagnetism, application studies to fundamental studies.

Flux quantization experiments indicate that the carriers, Cooper pairs (pairons), in the supercurrent have charge magnitude 2e, and that they move independently. Josephson interference in a Superconducting Quantum Int- ference Device (SQUID) shows that the centers of masses (CM) of pairons move as bosons with a linear dispersion relation. Based on this evidence we develop a theory of superconductivity in conventional and mate- als from a unified point of view. Following Bardeen, Cooper and Schrieffer (BCS) we regard the phonon exchange attraction as the cause of superc- ductivity. For cuprate superconductors, however, we take account of both optical- and acoustic-phonon exchange. BCS started with a Hamiltonian containing "electron" and "hole" kinetic energies and a pairing interaction with the phonon variables eliminated. These "electrons" and "holes" were introduced formally in terms of a free-electron model, which we consider unsatisfactory. We define "electrons" and "holes" in terms of the cur- tures of the Fermi surface. "Electrons" (1) and "holes" (2) are different and so they are assigned with different effective masses: Blatt, Schafroth and Butler proposed to explain superconductivity in terms of a Bose-Einstein Condensation (BEC) of electron pairs, each having mass M and a size. The system of free massive bosons, having a quadratic dispersion relation: and moving in three dimensions (3D) undergoes a BEC transition at where is the pair density.

Volume 9 of the "Handbook of Magnetic Materials" has a dual purpose, as do the preceding volumes in the series. As a textbook it is intended to be of assistance to those who wish to be introduced to a given topic in the field of magnetism without the need to read the vast amount of literature published. As a work of reference it is intended for scientists active in magnetism research. To this dual purpose, Volume 9 of the Handbook is composed of topical review articles written by leading authorities. In each of these articles an extensive description is given in graphical as well as in tabular form, much emphasis being placed on the discussion of the experimental material in the framework of physics, chemistry and material science.

Chapter one presents a general account of the magnetism of heavy-fermion systems. Two novel experimental techniques are described in chapters two and five. Chapter two deals with muon spin rotation and chapter five gives an account of the possibilities offered by photon beam spectroscopy. In both chapters it is shown how these sophisticated experimental methods can be used to obtain experimental information not easily obtainable by conventional experimental methods. Chapter three deals with interstitially modified intermetallic compounds of rare earth and 3d elements. Finally chapter four is concerned with thermodynamic approach to phase transitions and shows how the understanding and description of these magnetic phase transitions can be considerably enriched.
