A Uniform GTD Analysis of the Scattering of Electromagnetic Waves by a Smooth Convex Surface.

Abstract

An approximate asymptotic high frequency solution is obtained for the field exterior to a smooth, perfectly conducting convex surface when it is excited by a ray optical electromagnetic field. This asymptotic solution is uniform in the sense that it is valid within the transition regions adjacent to the shadow boundaries where the pure ray optical solution based on the geometrical theory of diffraction (GTD) fails, and it reduces to the GTD solution in terms of the incident, reflected, and surface diffracted ray.
