In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at Polytechnic University (at that time named the Polytechnic Institute of Brooklyn). MRI gained worldwide recognition in the 50s and 60s for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components, and devices. It was also known through its series of 24 topical symposia and the widely distributed hardbound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the institute currently conducts research in such areas as electromagnetic propagation and antennas, ultrabroadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid-state materials, quantum electronics, electromagnetic launchers, and networks. Following MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. Previous conferences in this series were: Directions in Electromagnetic Wave Modeling; October 1990 Ultra-Wideband Short-Pulse Electromagnetics; October, 1992 Ultra-Wideband Short-Pulse Electromagnetics, II; October, 1994 The proceedings of these conferences were also published by Plenum Press. This volume constitutes the proceedings of the fourth WRI International Conference dealing with Guided-Wave Optoelectronics: Device Characterization, Analysis and Design. The conference was held October 26-28, 1994, at the Polytechnic University in Brooklyn, New York, in cooperation with the IEEE Lasers and Electro Optics Society, and with the Optical Society of America.

The mathematical physicist and engineer William Thomson, 1st Baron Kelvin (1824 1904) is best known for devising the Kelvin scale of absolute temperature and for his work on the first and second laws of thermodynamics. The lectures in this collection demonstrate an attempt by Baron Kelvin to formulate a physical model for the existence of ether. This concept of a medium for light propagation became prominent in the late nineteenth century, arising from the combination of Maxwell's equations stating that light is an electromagnetic wave with the demands of Newtonian physics that light must move in a unique reference frame. First published in 1904, Kelvin's lectures describe the difficulties inherent in this model. These problems with the concept of ether are credited for inspiring Einstein to devise the theory of special relativity and the photoelectric effect, both of which are central to modern physics.

This book describes the ultra-short laser–matter interactions from the subtle atomic motion to the generation of extreme pressures inside the bulk of a transparent crystal. It is the successor to Femtosecond Laser–Matter Interactions: Theory, Experiment and Applications (2011). Explanation and experimental verification of the exceptional technique for the phase transformations under high pressure are in the core of the book. The novel phase formation occurs along the unique solid-plasmasolid transformation path: the memory of the initial state is lost after conversion to plasma. New phase forms from chaos during the cooling to the ambient. The pressure-affected material remains detained inside a pristine crystal at the laboratory tabletop. Unique super-dense aluminium and new phases of silicon were created by the confined micro-explosions. The text also describes the recent studies that used the quasi-non-diffracting Bessel beams. The applications comprise the new high-pressure material formation and micromachining. The book is an appealing source for readers interested in the cutting-edge research exploring extreme conditions and creating nanostructures at the laboratory tabletop.

Carbon forms a variety of allotropes due to the diverse hybridization of s- and p-electron orbitals, including the time-honored graphite and diamond as well as new forms such as C60 fullerene, nanotubes, graphene, and carbyne. The new family of carbon isotopes-fullerene, nanotubes, graphene, and carbyne-is called "nanostructured carbon" or "nanocarbon." These isotopes exhibit extreme properties such as ultrahigh mechanical strength, ultrahigh charge-carrier mobility, and high thermal conductivity, attracting considerable attention for their electronic and mechanical applications as well as for exploring new physics and chemistry in the field of basic materials science. Electron sources are important in a wide range of areas, from basic physics and scientific instruments to medical and industrial applications. Carbon nanotubes (CNTs) and graphene behave as excellent electron-field emitters owing to their exceptional properties and offer several benefits compared to traditional cathodes. Field emission (FE) produces very intense electron currents from a small surface area with a narrow energy spread, providing a highly coherent electron beam-a combination that not only provides us with the brightest electron sources but also explores a new field of electron beam-related research. This book presents the enthusiastic research and development of CNT-based FE devices and focuses on the fundamental aspects of FE from nanocarbon materials, including CNTs and graphene, and the latest research findings related to it. It discusses applications of FE to X-ray and UV generation and reviews electron sources in vacuum electronic devices and space thrusters. Finally, it reports on the new forms of carbon produced via FE from CNT.

Simultaneously storing both spectral and spatial information, 3D spectroscopy offers a new way to tackle astrophysical problems, and opens up new lines of research. Since its inception in the eighties and early nineties, research in this field has grown enormously. Large telescopes all around the world are now equipped with integral field units, and two instruments of the future James Webb Space Telescope will have integral field spectroscopic capabilities. Nowadays, more effort is dedicated to refining techniques for reducing, analyzing and interpreting the data obtained with 3D spectrographs. Containing lectures from the seventeenth Winter School of the Canary Islands Astrophysics Institute, this book explores new 3D spectroscopy techniques and data. A broad and balanced presentation of research in this field, it introduces astronomers to a new generation of instruments, widening the appeal of integral field spectroscopy and helping it become a powerful tool in tackling astrophysical problems.

This work provides a convincing motivation for and introduction to magnon-based computing. The challenges faced by the conventional semiconductor-transistor-based computing industry are contrasted with the many exciting avenues for developing spin waves (or magnons) as a complementary technology wherein information can be encoded, transmitted, and operated upon: essential ingredients for any computing paradigm. From this general foundation, one particular operation is examined: phase conjugation via four-wave-mixing (FWM). The author constructs an original theory describing the generation of a phase conjugate mirror with the remarkable property that any incident spin wave will be reflected back along the same direction of travel. After establishing a theoretical framework, the careful design of the experiment is presented, followed by the demonstration of a magnetic phase conjugate mirror using four-wave mixing for the first time. The thesis concludes with an investigation into the unexpected fractal behaviour observed arising from the phase conjugate mirror - a result that is testament to the richness and vibrancy of these highly nonlinear spin wave systems.

Solitons are a fascinating topic for study and a major source of interest for potential application in optical communication. Possibly the first observation of a soliton occurred in 1838 and was made by a clerical gentleman riding a horse along a canal towpath. When a barge under tow came to a stop alongside him the bow wave did not stop, but continued to travel on its own for several miles with no change in shape. At the time this unusual phenomenon was not understood and remained unexplained. Interest was revived with the development of optical fibres and the realisation that at the high intensities possible in their very small cores the onset of non-linear effects could modify the propagation characteristics in a significant way. In a seminal paper in 1973 Hasegawa and Tappert solved a non-linear Schrodinger equation for fibre propagation and found solutions for solitary waves, i.e. solitons. Since then advances have been very rapid resulting in a much better understanding of a wide variety of soliton effects, and, crucially, the realisation that soliton propagation can be used to potentially great advantage in practical long-distance systems. There is, as a result, a wealth of theoretical and experimental research in progress all over the world. At NTT (Japan) a pule-code-modulated soliton train has been transmitted at 10Gbit/s over one million kilometres with zero error! Perhaps all long-distance, large bandwidth communication problems have been solved for ever. This book gives a clear account of the theory and mathematics of solitons travelling in optical fibres. It is written by the authority on the subject.

These proceedings comprise of invited and contributed papers presented at the 13th International Conference on X-Ray Lasers (ICXRL 2012) which was held 11 15 June 2012 in Paris, France, in the famous Quartier Latin, inside the historical Center of Cordeliers. This conference is part of a continuing series dedicated to recent developments and applications of x-ray lasers and other coherent x-ray sources with attention to supporting technologies and instrumentation.
New results in the generation of intense coherent x-rays and progress towards practical devices and their applications are reported in these proceedings, including areas of research in plasma-based x-ray lasers, 4th generation accelerator-based sources and higher harmonic generation.
Recent achievements related to the increase of the repetition rate up to 100 Hz and shorter wavelength collisional plasma-based soft x-ray lasers down to about 7 nm are presented. Seeding the amplifying plasma with a femtosecond high-order harmonic of infrared laser was foreseen as the required breakthrough to break the picosecond frontier. Numerical simulations based on the Maxwell-Bloch model are presented in these proceedings, transposing the chirped pulse amplification technique to the x-ray domain in order to increase the time over which the femtosecond seed can be amplified.
These proceedings also include innovative applications of soft x ray lasers based on techniques and diagnostics relevant to topical domains such as EUV lithography, inertial confinement fusion, or warm dense matter physics."

This book offers readers a comprehensive, detailed analysis and treatment of optical waveguides (fiber, slab), an essential component of ultra-high bandwidth long, medium and short-haul telecommunication. The author describes an analysis scheme for optical waveguides that combines both geometric|ray optics and Maxwell's equations-based classical electrodynamics. This unique approach enables readers to develop an intuitive understanding of this topic, starting with macro properties, e.g., V parameter of an optical fiber, and progressively refining the analysis to individual modes of propagation through an optical waveguide. An exhaustive set of diagrams highlight the key features of an optical waveguide property, such as acceptance angle, meridional and skew rays in an optical fiber, or signal attenuation and dispersion in an optical waveguide. The author also provides a set of ready-to-use, ANSI C executables (for both Linux and Windows) that enable the reader to e.g, determine the allowed propagation modes (even, odd TE|TM) of a graded, step index optical fiber and a slab waveguide. Offers readers a single-source reference to the analysis and design of optical waveguides; Begins with macro-level analysis of the properties of optical waveguides and dives deeply into details in a step-by-step manner, enabling readers to develop an intuitive understanding; Includes C language executables, along with optical waveguide analysis and design examples to demonstrate their use in context.
