Generalized Ray Optical Analysis of Reflection from a Smooth Convex Conducting Surface.

Abstract

In certain applications involving reflection from smooth convex surfaces, the conventional geometrical optics method (GO) is not sufficiently accurate. In this paper a generalization of the conventional GO formulas is presented and closed-form expressions are derived. The derivation of the generalized geometrical optics (GGO) forumulas is based on the Fresnel transformation between two planes, one of which contains the spectral point, while the other passes through the observation point. The method developed herein improves the accuracy of GO with paying the high numerical cost of the physical optics integration. It is important, in particular, for computing the reflection characteristics of numerically specified surfaces. (Author
