Numerical solutions for the scattered fields from rough surfaces using the full wave generalized teclegraphists' equations

摘要

A numerical method is used to solve the integro-differential generalized telegraphists' equations for the total (single and multiple) diffusely scattered radiation wave amplitudes. These equation were derived using a full wave approach. The singularities of the scattering coefficients are removed on integrating by parts. A stationary phase approximation is used to obtain the far fields. The numerical solutions are obtained for one-dimensional deterministic surfaces. The numerical results for the total (single and multiple) diffusely scat4tered fields are in good agreement with the earlier single scatter analytical results when the maximum surface slope is less than 30 degrees.
