This book is devoted to resonant energy conversion in power electronics. It is a practical, systematic guide to the analysis and design of various dc-dc resonant inverters, high-frequency rectifiers, and dc-dc resonant converters that are building blocks of many of today's high-frequency energy processors. Designed to function as both a superior senior-to-graduate level textbook for electrical engineering courses and a valuable professional reference for practicing engineers, it provides students and engineers with a solid grasp of existing high-frequency technology, while acquainting them with a number of easy-to-use tools for the analysis and design of resonant power circuits. Resonant power conversion technology is now a very hot area and in the center of the renewable energy and... Less

This book is the first to give a comprehensive description of the physics and applications of resonant tunneling diodes. The opening chapters of the book set out the basic principles of coherent tunneling theory. The authors describe in detail the effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution, and intrinsic bistabilities. They review the applications of RTDs, such as in high-frequency signal generation and multi-valued data storage, and close the book with a chapter on the new field of resonant tunneling through laterally confined zero-dimensional structures. Covering all the key theoretical and experimental aspects of this active area of research, the book will be of great value to graduate students of quantum transport physics and device engineering,...

Electromagnetic metamaterials- from fundamental physics to advanced engineering applicationsThis book presents an original generalized transmission line approach associated with non-resonant structures that exhibit larger bandwidths, lower loss, and higher design flexibility. It is based on the novel concept of composite right/left- handed (CRLH) transmission line metamaterials (MMs), which has led to the development of novel guided-wave, radiated-wave, and refracted-wave devices and structures.The authors introduced this powerful new concept and are therefore able to offer readers deep insight into the fundamental physics needed to fully grasp the technology. Moreover, they provide a host of practical engineering applications.The book begins with an introductory chapter that places... Less

A violin is crafted of about 80 parts, together weighing in at little over one pound. It's a delicate structure that is precisely engineered to withstand nearly 70 pounds of string tension. To the untrained eye, all violins may look alike. To the expert, however, no two instruments are identical. Today, Lewis instruments are crafted in the same tradition as they were a century ago. These violas are constructed of properly aged premium wood for the most resonant sounding instruments, and still carefully hand adjust each instrument to meet or exceed the critical tolerances established by the Music Educators National Conference. Lewis calls this process "Stradjustment"; a patent, final adjustment procedure that guarantees every Lewis instrument lives up to its fullest potential.
