Book Description
Providing cutting-edge research on nanoelectronics and photonic devices and its application in future integrated circuits, this state-of-the-art book tackles the challenges of the different detailed theoretical and analytical models of solving the problems of various nanodevices. The volume also explores from different angles the roles of material composition and choice of materials that now play the most critical role in determining outcomes of low-dimensional nanoelectronic devices. The applications of those findings are extremely beneficial for the computing and telecommunication industries. Beginning with a solid theoretical background for every chapter, this volume covers the hottest areas of present-day electronic engineering. The continuous miniaturization of devices, components, and systems requires corresponding cutting-edge theoretical analysis supported by simulated findings before actual fabrication. That purpose is given maximum focus in this volume, which has interdisciplinary appeal, making it a comprehensive technological volume that deals with underlying aspects of physics, materials, structures in nano-regime, and the corresponding end-product in the form of devices.

Book Description
This new addition to the prestigious Wiley Series in Microwave and Optical Engineering presents the first comprehensive coverage of Frequency Selective Surfaces (FSS) and active grid arrays, the two-dimensional periodically arranged array elements which may be etched on, or imbedded in, one or multiple layers of dielectric laminates. Because of its filtering frequency properties, this technology, which has attracted much interest over the past two decades, is being used to create filtering devices in microwave and higher frequency bands. With Frequency Selective Surface and Grid Array, it is no longer necessary to sift through a multitude of research papers and reports. Here, in one self-contained volume, is a thorough and up-to-date treatment of the concept, theory, applications, design, and fabrication techniques for periodic arrays. Furthermore, the book provides a complete reference for the technological advances in FSS, including the recent technology of active grid arrays. The first part of the book is devoted to the fundamentals and analytical techniques pertaining to FSS and grid arrays, including the advanced analyses of the conjugate gradient method and the generalized mode-matching technique with multiple dielectrics or nonsimilar grid arrays. In the second part, the book deals with implementation and application, describing the numerous applications of this technology, from the reflector antenna system used in satellite and spacecraft communications and bandpass radome to solar energy grids. The expert contributions to this volume make it useful both as a tutorial and as a reference for project and system/design engineers working with antennas, optics, millimeter waves, microwaves, radar, and low observable radomes. A comprehensive and self-contained reference for FSS and grid array technology Frequency Selective Surfaces (FSS), the two-dimensional periodic array elements with frequency filtering properties, have made important advances over the past two decades. They provide filtering devices in microwave and higher frequency bands with applications ranging from bandpass radome to solar energy grids—including satellite and spacecraft communications. Written by experts in the field and edited by Dr. T. K. Wu, an internationally recognized researcher in electromagnetics, Frequency Selective Surface and Grid Array provides the first comprehensive look at the theory, measurements, manufacturing, and applications of FSS and grid array technology. This publication brings together a wealth of information previously not available in book form, as well as material that has not been published anywhere, including: Passive and active grid design concepts and analysis, as well as FSS materials and fabrication techniques Practical design of frequency selective surface, high-performance bandpass radome, and active grid array Detailed equations for the reaction integrals Three computer codes to get readers started in the design of FSS and grid array (disk included) Case studies of FSS applications to multiband communication antenna systems Tables, figures, references, and numerous examples of practical FSS and grid array designs A tutorial analysis that includes the multilayer grid and dielectrics Frequency Selective Surface and Grid Array is an invaluable planning and design resource for research engineers and scientists dealing with FSS and grid array, as well as a handy reference for students and professionals entering the field.

Book Description
"...Ben has been the world-wide guru of this technology, providing support to applications of all types. His genius lies in handling the extremely complex mathematics, while at the same time seeing the practical matters involved in applying the results. As this book clearly shows, Ben is able to relate to novices interested in using frequency selective surfaces and to explain technical details in an understandable way, liberally spiced with his special brand of humor... Ben Munk has written a book that represents the epitome of practical understanding of Frequency Selective Surfaces. He deserves all honors that might befall him for this achievement." -William F. Bahret. Mr. W. Bahret was with the United States Air Force but is now retired. From the early 50s he sponsored numerous projects concerning Radar Cross Section of airborne platforms in particular antennas and absorbers. Under his leadership grew many of the concepts used extensively today, as for example the metallic radome. In fact, he is by many considered to be the father of stealth technology. "This book compiles under one cover most of Munk's research over the past three decades. It is woven with the physical insight that he has gained and further developed as his career has grown. Ben uses mathematics to whatever extent is needed, and only as needed. This material is written so that it should be useful to engineers with a background in electromagnetics. I strongly recommend this book to any engineer with any interest in phased arrays and/or frequency selective surfaces. The physical insight that may be gained from this book will enhance their ability to treat additional array problems of their own." -Leon Peters, Jr. Professor Leon Peters, Jr., was a professor at the Ohio State University but is now retired. From the early sixties he worked on, among many other things, RCS problems involving antennas and absorbers. This book presents the complete derivation of the Periodic Method of Moments, which enables the reader to calculate quickly and efficiently the transmission and reflection properties of multi-layered Frequency Selective Surfaces comprised of either wire and/or slot elements of arbitrary shape and located in a stratified medium. However, it also gives the reader the tools to analyze multi-layered FSS's leading to specific designs of the very important Hybrid Radome, which is characterized by constant band width with angle of incidence and polarization. Further, it investigates in great detail bandstop filters with large as well as narrow bandwidth (dichroic surfaces). It also discusses for the first time, lossy elements used in producing Circuit Analog absorbers. Finally, the last chapter deals with power breakdown of FSS's when exposed to pulsed signals with high peak power. The approach followed by most other presentations simply consists of expanding the fields around the FSS, matching the boundary conditions and writing a computer program. While this enables the user to obtain calculated results, it gives very little physical insight and no help in how to design actual multi-layered FSS's. In contrast, the approach used in this title analyzes all curves of desired shapes. In particular, it discusses in great detail how to produce radomes made of FSS's located in a stratified medium (Hybrid Radomes), with constant band width for all angles of incidence and polarizations. Numerous examples are given of great practical interest. More specifically, Chapter 7 deals with the theory and design of bandpass radomes with constant bandwidth and flat tops. Examples are given for mono-, bi- and tri-planar designs. Chapter 8 deals with bandstop filters with broad as well as narrow bandwidth. Chapter 9 deals with multi-layered FSS of lossy elements, namely the so-called Circuit Analog Absorbers, designed to yield outstanding absorption with more than a decade of bandwidth. Features material previously labeled as classified by the United States Air Force.
