Computeraided modeling for analysis of arbitrary scatterers and feeds
Abstract
Surface integral equations are formulated to relate the radiation and scattering fields of primary feeds and scatterers to the current distributions on their surface. These currents are determined by reducing surface integral equations to a matrix equation via a moment method. The computed currents are utilized to determine the copolar and crosspolar fields of feeds and the far field of the scatterers. The technique is subsequently applied to study the radar crosssection of complex geometries such as conducting and dielectric spheres, finite cylinders, cubes and prisms, as well as to the rectangular waveguides representing an antenna problem. The developed method is general enough to handle various antenna and scattering problems and to generate solutions with a high degree of accuracy.
