Available in PDF, EPUB and Kindle. Book excerpt: An N-port loaded scatterer is one having N ports to which lumped impedance loads or a load network is connected. Methods are given to determine the characteristic modes of a loaded scatterer and for using them in a modal solution for electromagnetic scattering. A procedure is also given for resonating any given real port current, which makes that current the dominant mode of the loaded scatterer. The theory is formulated both in terms of open-circuit and short-circuit network parameters. A number of numerical examples are given for a wire triangle to illustrate the general theory. Computer programs are included for all procedures discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The considerable growth of RFID is currently accompanied by the development of numerous identification technologies that complement those already available while seeking to answer new problems. Chipless RFID is one example.The goal is to both significantly reduce the price of the tag and increase the amount of information it contains, in order to compete with the barcode while retaining the benefits of a flexible reading approach based on radio communication.To solve the problem of the number of bits, this book describes the possibility of coding the information at the level of the overall shape of the RCS of the tag, which would facilitate reaching very large quantities. The design of the tags then returns to the resolution of the inverse problem of the electromagnetic signature. The proposed design methodology regularizes the problem by decomposing the signature on a basis of elementary patterns whose signature is chosen in advance. - Includes a theoretical presentation of scattering phenomenon in electromagnetism, regrouping elements from classical RFID, pulse radar, and antenna theory - Features a new coding technique based on magnitude level that is presented and characterized for different kinds of tags - Proposes, for the first time, RCS synthesis based on a physical approach for wide-frequency bands

Book excerpt: Describes how to systematically implement various characteristic mode (CM) theories into designs of practical antenna systems This book examines both theoretical developments of characteristic modes (CMs) and practical developments of CM-based methodologies for a variety of critical antenna designs. The book is divided into six chapters. Chapter 1 provides an introduction and discusses the recent advances of the CM theory and its applications in antenna engineering. Chapter 2 describes the formulation of the characteristic mode theory for perfectly electrically conducting (PEC) bodies and discusses its numerical implementations. Chapter 3 presents the CM theory for PEC structures embedded in multilayered medium and its applications. Chapter 4 covers recent advances in CM theory for dielectric bodies and also their applications. Chapter 5 discusses the CM theory for N-port networks and its applications to the design of antenna arrays. Finally, Chapter 6 discusses the design of platform-integrated antenna systems using characteristic modes. This book features the following: Introduces characteristic mode theories for various electromagnetic structures including PEC bodies, structures in multilayered medium, dielectric bodies, and N-port networks Examines CM applications in electrically small antennas, microstrip patch antennas, dielectric resonator antennas, multiport antennas, antenna arrays, and platform mounted antenna systems Discusses numerical algorithms for the implementation of the characteristic mode theories in computer code Characteristic Modes: Theory and Applications in Antenna Engineering will help antenna researchers, engineers, and students find new solutions for their antenna design challenges.

Available in PDF, EPUB and Kindle. Book excerpt: Optimization of the field scattered by an antenna has important application in radar systems and as elements in passive communication links. A method is given for optimizing the scattering from a linear array of half-wavelength dipoles at a prescribed bistatic angle. The array is excited by a plane wave incident at an arbitrarily specified angle. The field scattered by the array is maximized or minimized as a function of the parameters of a network connected to the accessible minimized as a function of the parameters of a network connected to the accessible antenna terminals. The result is a matrix eigenvalue equation of order 1/2M(M-1) for the optimum parameters of an M element array. Passive solutions are constructed which yield a prescribed zero in the bistatic scattering pattern. The corresponding network can then be realized using existing network synthesis procedures. The essential features of the theory are illustrated by synthesizing an optimum network for a two element array. It is also shown that backscatter at any angle can be minimized independently of the receiving pattern of the array. (Author).
