Informationen zum Autor BEN A. MUNK, PhD, is Professor Emeritus of Electrical Engineering at Ohio State University and a major contributor to the theory and design of periodic structures, particularly frequency selective surfaces, circuit analog absorbers, and phased arrays. Klappentext A periodic surface is an assembly of identical elements arranged in a one or two-dimensional array. Such surfaces have various effects on incident electromagnetic waves. Their applications range from antennas to stealth aircraft.This book discusses finite antenna arrays and how to minimize the radar cross section of these arrays."Ben has been the world-wide guru of this technology...Ben Munk has written a book that represents the epitomy of practical understanding." W. Bahret, United States Air ForceFrequency selective surfaces (FSSs) have important military and civilian applications including antenna theory, satellite communications and stealth technologyAuthor is an authory on the subject, having been instrumental in the development of stealth technology for the US Air ForceMuch of the material in this book was deemed classified due to its importance to defence Zusammenfassung A periodic surface is an assembly of identical elements arranged in a one or two-dimensional array.
