Integral Solution for Diffraction Problems Involving Conducting Surfaces with Complex Geometries. 1. Theory
Abstract
For an arbitrary conducting surface Z(x,y) we obtained an analytical expression for the local refractive index nu as a function of Z, (delta Z/del x), (delta Z/delta y), and the Drude conductivity sigma by using the complex ray-tracing method. The Fresnel coefficients of reflectance and transmittance are then employed, and the value of nu is obtained to determine the scattered and refracted fields. The proposed method has advantages over the methods of solution by the Debye potential, the Laplace transform, and the vector wave equation in the computation of the scattering and absorption parameters of a wide range of complex surface and wave front geometries. The surface integrals obtained in the present study include the surface function in an explicit and concise form.
