The drive toward smaller and smaller electronic componentry has huge implications for the materials currently being used. As quantum mechanical effects begin to dominate, conventional materials will be unable to function at scales much smaller than those in current use. For this reason, new materials with higher electrical permittivity will be required, making this is a subject of intensive research activity within the microelectronics community. High k Gate Dielectrics reviews the state-of-the-art in high permittivity gate dielectric research. Consisting of contributions from leading researchers from Europe and the USA, the book first describes the various deposition techniques used for construction of layers at these dimensions. It then considers characterization techniques of the physical, chemical, structural, and electronic properties of these materials. The book also reviews the theoretical work done in the field and concludes with technological applications.

This volume highlights the recent advances and state of art in the experimental and theoretical studies of organometallic magnets. A plethora of organic ligands such as Mannich-base derivatives, redox-active chromophores, cyanides, Schiff base among others are used to coordinate to 3d transition metals, 4f lanthanides and 5f actinides to design the molecular magnets. Deep analysis of the coordination sphere symmetry, electronic distribution, luminescence are investigated to perform magneto-structural correlation leading to a better understanding of the magnetic properties. Furthermore, the rationalization of the magnetic behavior can be reached using ab initio calculations. The multiple applications that these molecular magnets offer could revolutionize the high-density data storage, spintronics and quantum computing technologies. This volume provides a discussion of these topics from leading international experts and will be a useful reference for researchers working in this field.

Topological Foundations of Electromagnetism seeks a fundamental understanding of the dynamics of electromagnetism; and marshals the evidence that in certain precisely defined topological conditions, electromagnetic theory (Maxwell's theory) must be extended or generalized in order to provide an explanation and understanding of, until now, unusual electromagnetic phenomena. Key to this generalization is an understanding of the circumstances under which the so-called A potential fields have physical effects. Basic to the approach taken is that the topological composition of electromagnetic fields is the fundamental conditioner of the dynamics of these fields. The treatment of electromagnetism from, first, a topological perspective, continuing through group theory and gauge theory, to a differential calculus description is a major thread of the book. Suggestions for potential new technologies based on this new understanding and approach to conditional electromagnetism are also given.

As technology matures, communication system operation regions shift from mic- wave and millimeter ranges to sub-millimeter ranges. However, device perf- mance at very high frequencies suffers drastically from the material de?ciencies. As a result, engineers and scientists are relentlessly in search for the new types of materials, and composites which will meet the device performance requirements and not present any de?ciencies due to material electrical and magnetic properties. Anisotropic and gyrotropic materials are the class of the materials which are very important in the development high performance microwave devices and new types composite layered structures. As a result, it is a need to understand the wave propagation and radiation characteristics of these materials to be able to realize them in practice. This book is intended to provide engineers and scientists the required skill set to design high frequency devices using anisotropic, and gyrotropic materials by providing them the theoretical background which is blended with the real world engineering application examples. It is the author's hope that this book will help to ?ll the gap in the area of applied electromagnetics for the design of microwave and millimeter wave devices using new types of materials. Each chapter in the book is designed to give the theory ?rst on the subject and solidify it with application examples given in the last chapter. The application examples for the radiation problems are given at the end of Chap. 5 and Chap. 6 for anisotropic and gyrotropic materials, respectively, after the theory section.

A practical one-volume guide to anechoic chamber designs for electromagnetic measurements

The electromagnetic anechoic chamber has been with us since it was invented at the Naval Research Laboratory in Washington, DC, in the early 1950s. Just about every major aerospace company has large numbers of them located throughout the United States and the world. Now, because of the stringent electromagnetic interference requirements that must be considered in the development of all new electronic products, these facilities are appearing in the automotive, telecommunications, aerospace, computer, and other industries.

This handbook provides the designer/procurer of electromagnetic chambers with a single source of practical information on the full range of anechoic chamber designs. It reviews the current state of the art in indoor electromagnetic testing facilities and their design and specifications. You’ll find information on a large variety of anechoic chambers used for a broad range of electromagnetic measurements that are commonly conducted in indoor test facilities as well as details on:

• Measurement theory to support the chamber design procedures provided in each of the specific chamber designs
• Test facilities for the measurement of antennas, scattering (RCS), and electromagnetic compatibility

Unlike traditional NMR textbooks for chemists, this fresh look at the topic combines theory, technology and application in a wide range of fields, targeting biochemists, medicinal chemists, and structural biologists, as well as organic chemists. The text has been developed from a one-semester graduate-level course taught by the authors at the University of Zurich, and offers numerous intuitive illustrations, training exercises and plain-language explanations of complex theory. Divided into four major parts, the first introduces the theory, providing a profound understanding of why experiments work, without a rigorous mathematical treatment of all the physico-chemical computations and deliberately shorter than in most other NMR textbooks. Part two discusses current instrumentation and practical aspects, including sample preparation, processing of raw data and the use of databases, while the third part focuses on the main application of NMR, with examples and training spectra taken from a wide range of synthetic and natural compounds. Part four introduces a selection of modern NMR applications in chemistry, biochemistry, medicinal chemistry and molecular biology, explaining the protocols used and how to interpret the results. With its focus on practical aspects and applications, this text will prove useful long after leaving college, by helping users to select experimental methods and in setting up and running their own NMR experiments.

A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices-or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity's essential role in all life is rooted in our observations of its influences on the body-influences governed by the body's central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals-from Benjamin Franklin to Elon Musk-Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand-and replicate-the ways electricity enables the body's essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize-winning discoveries of the electron and neuron, the history of experimentation involving electricity's effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

In magnetic systems of nano-meter size, the interplay between spin and charge of electrons provides unique transport phenomena. In magnetic superlattices, magnetic and non-magnetic metallic thin films with thickness of the order of one nano-meter are piled-up alternately. Since the discovery of giant magnetoresistance (GMR) in these superlattices in 1988, spin dependent transport phenomena in magnetic nanostructures have received much attention from both academic and technological points of view. Ferromagnetic tunnel junctions made of ferromagnetic metal electrodes and a very thin insulating barrier between them are also of current interest as magnetoresistive devices, where the tunneling current depends on the relative orientation of magnetization (TMR). In addition to magnetic superlattices and magnetic tunnel junctions, magnetic granular systems and magnetic dots have been studied extensively as magnetoresistive systems. Edited by two of the world's leading authorities, Spin Dependent Transport in Magnetic Nanostructures introduces and explains the basic physics and applications of a variety of spin-dependent transport phenomena in magnetic nanostructures with particular emphasis on magnetic multilayers and magnetic tunnel junctions.
