Rutgers University launched WINLAB in 1989, just as the communications industry, the Federal government, and the financial community in the United States, were waking up to the growing public appetite for wireless communications and to the shortage of technology to feed it. The secret was already out in Europe, where no fewer than three new cordless and cellular systems were progressing from drawing board to laboratory to factory to consumers. In July 1989, the FCC held a well-attended tutorial that turned into a debate over whether second generation British or Swedish technology held the key to mass-market personal communications. Many in the audience wondered whether United States technology was out of the picture. Technology uncertainties are more acute in wireless communications than in any other information service. For example multi-gigabit optical fiber communications have followed an orderly progression from basic science leading to technology, which in turn stimulated standards, and then commercial products. Eventually applications will be found and industry and society at large will reap the benefits. By contrast, the applications of wireless communications are apparent to an eager public. A large market exists but is held in check by a shortage of capacity. The demand has led the cellular industry to formulate standards for advanced systems before the technology is in place to implement them. Everyone holds their breath waiting to observe performance of the first products. Gaps in basic science add to the uncertainty and forestall the resolution of technological debates.

The traditional systems disciplines of communications, computation, control and signal processing are becoming increasingly important in addressing major technological challenges of the coming century, in fields such as materials processing, manufacturing automation, speech recognition and ubiquitous personal communications, among many others. Moreover the boundaries between these separate disciplines are being rapidly blurred by the many demands of these applications. This Tribute, dedicated to Thomas Kailath for his many seminal contributions to these areas, highlights several recent trends and results, described by leading scientists and engineers from around the world. The thirty-six papers in this volume present important results on, among others, interference cancellation in multipath channels, decision feedback equalization for packet transmission, blind equalization and smart antennas for mobile communications, displacement structure, fast and stable algorithms in numerical linear algebra, nonconvex optimization problems, issues in nanoelectronic computation, fundamental limits of control system performance, LQG control with communication constraints, nonlinear "H"INFINITY control, adaptive nonlinear control, model identification, tomographic deconvolution, and higher-order statistics. The applications discussed herein include packet radio, robotics, very flexible mechanical systems, power systems and power electronics, moving object detection, complexity management and several others. The volume starts out with a survey by Professor Kailath entitled Norbert Wiener and the Development of Mathematical Engineering', a term suggested by Wiener that can serve as a compactdescription of the variety of fields described herein.

"...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.

Micromachined scanning mirrors are interesting for a wide variety of applications because of their potential low cost, high speed, low power consumption, and reliability. These mirrors can offer significant advantages over macro-scale mirrors, but the fundamental limitations of scanning mirrors have not been widely discussed.
Miniaturization in electronic systems has led to radical improvements in computers and communications, and micromachining technologies promise to generate such improvements in miniaturized mechanical and optical systems, including specifically higher-speed, smaller, lower-cost scanning mirrors. Micromachined Mirrors provides an overview of the performance enhancements that will be realized by miniaturizing scanning mirrors like those used for laser printers and barcode scanners, and the newly enabled applications, including raster-scanning projection video displays and compact, high-speed fiber-optic components.
There are a wide variety of methods used to fabricate micromachined mirrors - each with its advantages and disadvantages. There are, however, performance criteria common to mirrors made from any of these fabrication processes. For example, optical resolution is related to the mirror aperture, the mirror flatness, and the scan angle. Micromachined Mirrors provides a framework for the design of micromirrors, and derives equations showing the fundamental limits for micromirror performance. These limits provide the micromirror designer tools with which to determine the acceptable mirror geometries, and to quickly and easily determine the range of possible mirror optical resolution and scan speed.
Micromachined Mirrors presents descriptions ofmirrors made from two fabrication processes - the surface-micromachining process and the staggered torsional electrostatic combdrive (STEC) high-aspect ratio micromachining process. The mirrors made using these two processes are evaluated for scan speed, optical resolution, ease of manufacture, and reliability.
Micromachined Mirrors also presents an example application of surface-micromachined mirrors: a raster-scanning projection video display. This demonstration shows the advantages of micromachined mirrors (small high-speed scanners) with special attention paid to the major drawback of surface-micromachined mirrors (lower resolution due to dynamic deformation). The successful demonstration of this simple prototype video display helps clarify the importance of the critical performance characteristics to consider when designing micromachined mirrors.
