This book presents an overview of finite element software. It discusses the capabilities and limitations of the available softwear and helps readers formulate engineering problems so that they fit into the framework of current software.

A survey of microwave technology tailored for professionals in wireless communications RF Technologies for Low Power Wireless Communications updates recent developments in wireless communications from a hardware design standpoint and offers specialized coverage of microwave technology with a focus on the low power wireless units required in modern wireless systems. It explores results of recent research that focused on a holistic, integrated approach to the topics of materials, devices, circuits, modulation, and architectures rather than the more traditional approach of research into isolated topical areas.Twelve chapters deal with various fundamental research aspects of low power wireless electronics written by world-class experts in each field. The first chapter offers an overview of wireless architecture and performance, followed by detailed coverage of: Advanced GaAs-based HBT designsInP-based devices and circuitsSi/SiGe HBT technologyNoise in GaN devicesPower amplifier architectures and nonlinearitiesPlanar-oriented componentsMEMS and micromachined componentsResonators, filters, and low-noise oscillatorsAntennasTransceiver front-end architecturesWith a clear focus and expert contributors, RF Technologies for Low Power Wireless Communications will be of interest to a wide range of electrical engineering disciplines working in wireless technologies.

The most comprehensive work on a number of practical numerical methods for analyzing passive structures in microwave and millimeter-wave integrated circuits. The introduction presents a brief comparison of the various numerical methods and how they may be integrated into computer-aided design programs, so the reader can make the appropriate choice. Chapters following present step-by-step, detailed descriptions of the methods, each chapter written by the utmost authority on the subject. Chapters provide illustrative examples and are written so that the reader can write his own computer program based on the numerical method described (some chapters include sample computer programs).

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 resonant type and transmission line metamaterials in historical perspective. The next six chapters give readers a solid foundation in the fundamentals and practical applications: Fundamentals of LH MMs describes the fundamental physics and exotic properties of left-handed metamaterialsTL Theory of MMs establishes the foundations of CRLH structures in three progressive steps: ideal transmission line, LC network, and real distributed structureTwo-Dimensional MMs develops both a transmission matrix method and a transmission line method to address the problem of finite-size 2D metamaterials excited by arbitrary sourcesGuided-Wave Applications and Radiated-Wave Applications present a number of groundbreaking applications developed by the authorsThe Future of MMs sets forth an expert view on future challenges and prospectsThis engineering approach to metamaterials paves the way for a new generation of microwave and photonic devices and structures. It is recommended for electrical engineers, as well as physicists and optical engineers, with an interest in practical negative refractive index structures and materials.
