Abstract

A full-wave theory of plane wave scattering from rough surfaces called the correction current (CC) method was recently developed. This paper extends the CC method to the more general case of beam wave scattering. Gaussian beams are assumed incident upon a deterministic metal rough surface. Scatter patterns based on the CC method are calculated and compared to scatter patterns determined by the method of moments solution of an electric field integral equation formulation of the scatter problem. It was shown that good agreement between these two solution methods is obtained for scatter surfaces for which the CC method is shown to satisfy conservation of power and an accuracy criterion.
