Designer Surfaces presents an approach to the design and fabrication of optical elements that are based on the use of one- or two-dimensional randomly rough surfaces to reflect or transmit light in specified ways. The reader is provided with an introduction to analytical methods for the solution of direct problems in rough surface scattering, and fabrication techniques. These can be useful in contexts outside the scope of this book. The advantages and disadvantages of this stochastic approach compared to the diffractive optics approach are discussed. Finally, experimental results that verify the predictions of the theories developed in this book are presented. Authority of authors The only book on the topic Derivations are given in detail, with many figures illustrating results

Surface texturing has been recognized as a method for enhancing the tribological properties of surfaces for many years. Adding a controlled texture to one of two faces in relative motion can have many positive effects, such as reduction of friction and wear and increase in load capacity. To date, the true potential of texturing has not been realized due to the severe lack of detailed information about the mechanistic functional details of texturing in a tribological situation. Inspiration and Design for Bio-Inspired Surfaces in Tribology: Emerging Research and Opportunities is a pivotal reference source that focuses on surface engineering techniques to mimic biological materials. Highlighting a broad range of topics including bio-mimetics, contact analysis, and thermodynamics, this book is ideally designed for engineers, environmentalists, academicians, researchers, and students.

Molecular surface science has made enormous progress in the past 30 years. The development can be characterized by a revolution in fundamental knowledge obtained from simple model systems and by an explosion in the number of experimental techniques. The last 10 years has seen an equally rapid development of quantum mechanical modeling of surface processes using Density Functional Theory (DFT). Chemical Bonding at Surfaces and Interfaces focuses on phenomena and concepts rather than on experimental or theoretical techniques. The aim is to provide the common basis for describing the interaction of atoms and molecules with surfaces and this to be used very broadly in science and technology. The book begins with an overview of structural information on surface adsorbates and discusses the structure of a number of important chemisorption systems. Chapter 2 describes in detail the chemical bond between atoms or molecules and a metal surface in the observed surface structures. A detailed description of experimental information on the dynamics of bond-formation and bond-breaking at surfaces make up Chapter 3. Followed by an in-depth analysis of aspects of heterogeneous catalysis based on the d-band model. In Chapter 5 adsorption and chemistry on the enormously important Si and Ge semiconductor surfaces are covered. In the remaining two Chapters the book moves on from solid-gas interfaces and looks at solid-liquid interface processes. In the final chapter an overview is given of the environmentally important chemical processes occurring on mineral and oxide surfaces in contact with water and electrolytes. Gives examples of how modern theoretical DFT techniques can be used to design heterogeneous catalysts This book suits the rapid introduction of methods and concepts from surface science into a broad range of scientific disciplines where the interaction between a solid and the surrounding gas or liquid phase is an essential component Shows how insight into chemical bonding at surfaces can be applied to a range of scientific problems in heterogeneous catalysis, electrochemistry, environmental science and semiconductor processing Provides both the fundamental perspective and an overview of chemical bonding in terms of structure, electronic structure and dynamics of bond rearrangements at surfaces

This thesis proposes a reliable and repeatable method for implementing Spoof Surface Plasmon (SSP) modes in the design of various circuit components. It also presents the first equivalent circuit model for plasmonic structures, which serves as an insightful guide to designing SSP-based circuits. Today, electronic circuits and systems are developing rapidly and becoming an indispensable part of our daily life; however the issue of compactness in integrated circuits remains a formidable challenge. Recently, the Spoof Surface Plasmon (SSP) modes have been proposed as a novel platform for highly compact electronic circuits. Despite extensive research efforts in this area, there is still an urgent need for a systematic design method for plasmonic circuits. In this thesis, different SSP-based transmission lines, antenna feeding networks and antennas are designed and experimentally evaluated. With their high field confinement, the SSPs do not suffer from the compactness limitations of traditional circuits and are capable of providing an alternative platform for the future generation of electronic circuits and electromagnetic systems.

"...Ben has been the world-wide guru of this technology, providingsupport to applications of all types. His genius lies in handlingthe extremely complex mathematics, while at the same time seeingthe practical matters involved in applying the results. As thisbook clearly shows, Ben is able to relate to novices interested inusing frequency selective surfaces and to explain technical detailsin an understandable way, liberally spiced with his special brandof humor... Ben Munk has written a book that represents the epitomeof practical understanding of Frequency Selective Surfaces. Hedeserves all honors that might befall him for this achievement."-William F. Bahret. Mr. W. Bahret was with the United States Air Force but is nowretired. From the early 50s he sponsored numerous projectsconcerning Radar Cross Section of airborne platforms in particularantennas and absorbers. Under his leadership grew many of theconcepts used extensively today, as for example the metallicradome. In fact, he is by many considered to be the father ofstealth technology. "This book compiles under one cover most of Munk's research overthe past three decades. It is woven with the physical insight thathe has gained and further developed as his career has grown. Benuses mathematics to whatever extent is needed, and only as needed.This material is written so that it should be useful to engineerswith a background in electromagnetics. I strongly recommend thisbook to any engineer with any interest in phased arrays and/orfrequency selective surfaces. The physical insight that may begained from this book will enhance their ability to treatadditional array problems of their own." -Leon Peters, Jr. Professor Leon Peters, Jr., was a professor at the Ohio StateUniversity but is now retired. From the early sixties he worked on,among many other things, RCS problems involving antennas andabsorbers. This book presents the complete derivation of the Periodic Methodof Moments, which enables the reader to calculate quickly andefficiently the transmission and reflection properties ofmulti-layered Frequency Selective Surfaces comprised of either wireand/or slot elements of arbitrary shape and located in a stratifiedmedium. However, it also gives the reader the tools to analyzemulti-layered FSS's leading to specific designs of the veryimportant Hybrid Radome, which is characterized by constant bandwidth with angle of incidence and polarization. Further, itinvestigates in great detail bandstop filters with large as well asnarrow bandwidth (dichroic surfaces). It also discusses for thefirst time, lossy elements used in producing Circuit Analogabsorbers. Finally, the last chapter deals with power breakdown ofFSS's when exposed to pulsed signals with high peak power. The approach followed by most other presentations simply consistsof expanding the fields around the FSS, matching the boundaryconditions and writing a computer program. While this enables theuser to obtain calculated results, it gives very little physicalinsight and no help in how to design actual multi-layered FSS's. Incontrast, the approach used in this title analyzes all curves ofdesired shapes. In particular, it discusses in great detail how toproduce radomes made of FSS's located in a stratified medium(Hybrid Radomes), with constant band width for all angles ofincidence and polarizations. Numerous examples are given of greatpractical interest. More specifically, Chapter 7 deals with thetheory and design of bandpass radomes with constant bandwidth andflat tops. Examples are given for mono-, bi- and tri-planardesigns. Chapter 8 deals with bandstop filters with broad as wellas narrow bandwidth. Chapter 9 deals with multi-layered FSS oflossy elements, namely the so-called Circuit Analog Absorbers,designed to yield outstanding absorption with more than a decade ofbandwidth.

A large part of this book is devoted to a study of possible design procedures for various types of lens or mirror systems, with fully worked examples of each. The reader is urged to follow the logic of these examples and be sure that he understands what is happening, noticing particularly how each available degree of freedom is used to control one aberration. Not every type of lens has been considered, of course, but the design techniques illustrated here can readily be applied to the design of other more complex systems. It is assumed that the reader has access to a small computer to help with the ray tracing, otherwise he may find the computations so time-consuming that he is liable to lose track of what he is trying to accomplish.
