Electrical Engineering Plane-Wave Theory of Time-Domain Fields Near-Field Scanning Applications A volume in the IEEE Press Series on Electromagnetic Wave Theory Donald G. Dudley, Series Editor Plane-Wave Theory of Time-Domain Fields provides a comprehensive framework for the formulation and solution of numerous problems involving the radiation, reception, propagation, and scattering of electromagnetic and acoustic waves. Green's function and plane-wave spectrum representations in both the time and frequency domains are systematically derived and effectively applied to the decomposition and analysis of transient and time-harmonic fields. With the publication of this book, probe-corrected near-field measurement techniques, which have previously been confined to the frequency domain, have been extended to ultra-wideband, short-pulse antennas and transducers. Featured topics include: * Fundamental theorems in electromagnetics and acoustics * A rigorous development of time-domain and frequency-domain plane-wave representations * Probe-corrected planar near-field scanning for time-domain and frequency-domain fields * Sampling theorems and computation schemes for time-domain and frequency-domain fields * The application of plane-wave theory to static electric and magnetic fields * Analytic-signal formulas that simplify the formulation and analysis of transient fields * Wave phenomena, such as "electromagnetic missiles" encountered only in the time domain * Definitive force and power relations for electromagnetic and acoustic fields and sources By combining unencumbered straightforward derivations with in-depth expositions of prerequisite material, the authors have created an invaluable resource for research scientists and engineers in electromagnetics and acoustics, and a definitive reference on plane-wave expansions and near-field measurements. 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 reprintings and revisions of recognized classics by established authors and researchers. Emphasis is on works of long-term archival significance in electromagnetic waves and applications. Designed specifically for graduate students, researchers and practicing engineers, the series provides affordable volumes that explore and explain electromagnetic waves beyond the undergraduate level.
About the Authors... Thorkild B. Hansen has worked for the past 10 years on research problems in electromagnetics and acoustics. Within high-frequency diffraction theory, he has developed methods for calculating scattering from corners, narrow grooves, and shadow boundaries. Dr. Hansen has also formulated planar and spherical near-field scanning techniques in the time domain, and derived exact beam representations that are alternatives to the classical multipole expansions. His recent work includes forward and inverse scattering problems for ground-penetrating and subsurface radars. Arthur D. Yaghjian s research at the National Institute of Standards and Technology, at the Air Force Research Laboratory, and most recently as an independent consultant in electromagnetics, has led to the development of exact, numerical, and high-frequency methods for predicting and measuring the near and far fields of antennas and scatterers. He has contributed to the determination of electromagnetic fields in continuous media and to the formulation of classical equations of motion of charged particles.
