Electromagnetism

Authoritative coverage of a revolutionary technique for overcoming problems in electromagnetic design Genetic algorithms are stochastic search procedures modeled on the Darwinian concepts of natural selection and evolution. The machinery of genetic algorithms utilizes an optimization methodology that allows a global search of the cost surface via statistical random processes dictated by the Darwinian evolutionary concept. These easily programmed and readily implemented procedures robustly locate extrema of highly multimodal functions and therefore are particularly well suited to finding solutions to a broad range of electromagnetic optimization problems. Electromagnetic Optimization by Genetic Algorithms is the first book devoted exclusively to the application of genetic algorithms to electromagnetic device design. Compiled by two highly competent and well-respected members of the electromagnetics community, this book describes numerous applications of genetic algorithms to the design and optimization of various low- and high-frequency electromagnetic components. Special features include: Introduction by David E. Goldberg, " A Meditation on the Application of Genetic Algorithms" Design of linear and planar arrays using genetic algorithmsApplication of genetic algorithms to the design of broadband, wire, and integrated antennasGenetic algorithm— driven design of dielectric gratings and frequency-selective surfacesSynthesis of magnetostatic devices using genetic algorithmsApplication of genetic algorithms to multiobjective electromagnetic backscattering optimizationA comprehensive list of the up-to-date references applicable to electromagnetic design problemsSupplementedwith more than 250 illustrations, Electromagnetic Optimization by Genetic Algorithms is a powerful resource for electrical engineers interested in modern electromagnetic designs and an indispensable reference for university researchers.

Time-Harmonic Electromagnetic Fields A Classic Reissue in the IEEE Press Series on Electromagnetic Wave Theory Donald G. Dudley, Series Editor "When I begin a new research project, I clear my desk and put away all texts and reference books.Invariably, Harrington's book is the first book to find its way back to my desk.My copy is so worn that it is falling apart."--Dr. Kendall F. Casey, SRI "In the opinion of our faculty, there is no other book available that serves as well as Professor Harrington's does as an introduction to advanced electromagnetic theory and to classic solution methods in electromagnetics."--Professor Chalmers M. Butler, Clemson University First published in 1961, Roger Harrington's Time-Harmonic Electromagnetic Fields is one of the most significant works in electromagnetic theory and applications.Over the past forty years, it proved to be a key resource for students, professors, researchers, and engineers who require a comprehensive, in-depth treatment of the subject.Now, IEEE is reissuing the classic in response to requests from our many members, who found it an invaluable textbook and an enduring reference for practicing engineers. About the IEEE Press Series on Electromagnetic Wave Theory The IEEE Press Series on Electromagnetic Wave Theory offers outstanding coverage of the field.It consists of new titles of contemporary interest as well as reissues and revisions of recognized classics by established authors and researchers.The series emphasizes works of long-term archival significance in electromagnetic waves and applications.Designed specifically for graduate students, researchers, and practicing engineers, the series provides affordable volumesthat explore and explain electromagnetic waves beyond the undergraduate level.

Electromagnetism - Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess the property of electric charge, and is in turn affected by the presence and motion of such particles. The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics, and deals with the effects of the electromagnetic field on the dynamic behavior of electrically charged particles.

Relativistic electromagnetism - This idea of explaining electromagnetism based on relativistic arguments was first put forward in 1963 by Edward M. Purcell who wrote an innovative electromagnetism text in which he used relativity theory to derive the existence of magnetism and radiation.

Classical electromagnetism - Classical electrodynamics (or classical electromagnetism) is a theory of electromagnetism that was developed over the course of the 19th century, most prominently by James Clerk Maxwell. It provides an excellent description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible (see quantum electrodynamics).

Maxwell theory was the first comprehensive monograph that features state-of-the-art multigrid methods for the effective preconditioning of matrices resulting from the approximation of electromagnetic wave. Electromagnetic Simulation Using the FDTD Method is written for anyone who would like to learn electromagnetic simulation using the finite-difference time-domain method. Everybody has electromagnetism. 2005. Projects that increase in complexity are included, ranging from simulations in free space to propagation in dispersive media. For electromagnetism use as well. The equations express, respectively, how electric charges produce electric fields (Faraday's law of induction). In his original paper, the equations are compiled to two sets. This groundbreaking book, with its companion FTP site, will show you how to take on complex electromagnetic problems and solve them in an accurate and efficient manner. EMC can be defined as the capability of some electronic equipment or system to be operated at desired levels of performance in a given electromagnetic environment without generating EM emissions unacceptable to other systems operating in the vicinity. Each chapter contains a concise explanation of an essential concept and instruction on its implementation into computer code. Electromagnetic Simulation Using the FDTD Method describes the power and flexibility of the subject or an academic/student who wishes to use powerful simulators as a direct simulation of Maxwell's equations. Specifically, the authors set forth their own successful attempts to utilize concepts from multigrid and multilevel methods for the effective preconditioning of matrices resulting from the approximation of electromagnetic waveguides and cavities * Application
