Approximate Boundary Conditions in Electromagnetics (Electromagnetic Waves) - Tapa dura

Non-metallic materials and composites are now commonplace in modern vehicle construction, and the need to compute scattering and other electromagnetic phenomena in the presence of material structures has led to the development of new simulation techniques. This book describes a variety of methods for the approximate simulation of material surfaces, and provides the first comprehensive treatment of boundary conditions in electromagnetics. The genesis and properties of impedance, resistive sheet, conductive sheet, generalised (or higher order) and absorbing (or non-reflecting) boundary conditions are discussed. Applications to diffraction by numerous canonical geometries and impedance (coated) structures are presented, and accuracy and uniqueness issues are also addressed, high frequency techniques such as the physical and geometrical theories of diffraction are introduced, and more than i 30 figures illustrate the results, many of which have not appeared previously in the literature. Written by two of the authorities m the field, this graduate-level text should be of interest to all scientists and engineers concerned with the analytical and numerical solution of electromagnetic problems.

T.B.A. Senior received his PhD from Cambridge University in 1954 and is now a Professor and Associate Chairman in the Department of Electrical Engineering and Computer Science at the University of Michigan. He is the author of two other books, numerous book chapters and over 200 journal articles on electromagnetic scattering. He is a Fellow of the IEEE, a Vice-President of the International Union of Radio Science and was the recipient of the 1993 van der Pol Gold Medal. J.L. Volakis is a Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan. He obtained his PhD from Ohio State University in 1982 and spent two years at Rockwell International working on the BIB aircraft programme before going to Michigan. He has published over 100 articles on computational and analytical methods in electromagnetics and was an Associate Editor of the IEEE Trans, on Antennas and Propagation. Currently he serves as an Associate Editor of Radio Science and edits the EM Programmer's notebook published in the IEEE Antennas and Propagation Magazine.
