Moment Method Solutions for Radiation and Scattering from Arbitrarily Shaped Surfaces.

Abstract

General quadrilateral surface-patch, thin-wire, and wire/plate attachment modes are developed for the moment method solution of electromagnetic scattering and antenna problems. The basic theory along with the techniques for accurate and efficient evaluation of the impedance elements are described. The methods to automatically set up the surface-patch modes for a polygonal plate are given. Numerical results for various antennas and scatterers are compared with other theoretical results and measurements. Using techniques developed in this work, the microstrip antenna is analyzed and the numerical results are also presented.
