An analog/hybrid computer solution of electromagnetic scattering problems
Abstract
Several techniques that may be used to solve exterior electromagnetic scattering problems are studied. Analytical methods, moment methods, subsectional methods, probabilistic methods, integral equation methods, and analog/hybrid computer methods were considered to determine the best method to use in a general approach to scattering problems. It was shown that while all these methods were able to solve certain classes of problems, no single technique qualified as a general solution method. A new scattering technique, the Unimoment - Monte Carlo method, was developed from the strengths and weaknesses of the more traditional methods. It is a probabilistic technique used to solve a deterministic problem. A description of the Unimoment - Monte Carlo computer system along with various factors influencing performance of the method is included.
