Informationen zum Autor Professor Jean Van Bladel is an eminent researcher and educator in fundamental electromagnetic theory and its application in electrical engineering. Over a distinguished career, he has been the recipient of many awards and honors. A Fellow of the IEEE, he was awarded the Henrich Hertz Medal of the IEEE in 1995 and the Distinguished Achievement Award of the IEEE Antennas and Propagation Society in 1997. With the International Union of Radio Science (URSI), he was secretary general from 1979 to 1993 and was named Honorary President in 1999. He is currently Professor Emeritus at Ghent University in Belgium. Klappentext The definitive reference on electromagnetic field, updated and expandedThis definitive text and reference on electromagnetic fields has been updated and expanded to twice its original content. It incorporates the latest methods, theory, formulations, and applications that relate to today's technologies. With an emphasis on basic principles and a focus on electromagnetic formulation and analysis, Electromagnetic Fields, Second Edition includes:*Detailed discussions of electrostatic fields, potential theory, propagation in waveguides and unbounded space, scattering by obstacles, penetration through apertures, and field behavior at high and low frequencies*Many analytical developments suitable for exploitation by the numerical analyst, including the popular method of moments*Comprehensive discussion of singularities of sources and fields with delineations of field properties at edges and at sector and cone vertices*Extensive appendices that of themselves are worth the cost of the book*A large, useful, carefully compiled set of referencesWith descriptions of methods for solving problems and with many applications of theory to electromagnetic engineering, this is a valuable resource for students, professors, and practicing engineers. It is also a comprehensive textbook for graduate-level courses in various aspects of electromagnetic theory. Zusammenfassung To complete the IEEE-Wiley offering in Electromagnetic Theory, this is an important and current revision in a field where our most current text was published in 1991. Responds to the increased interest of the electro-mechanical community in field problems by including numerous examples throughout the text. Inhaltsverzeichnis Preface xiii 1.
