Scattering and Depolarization of Electromagnetic Waves--Full Wave Solutions.
Abstract
Traditionally physical optics and perturbation theories have been used to derive the like and cross polarized scattering cross sections for composite random rough surfaces. To this end two scale models have been adopted and the rough surfaces are regarded as small scale surface perturbations that are superimposed on large scale, filtered surfaces. Thus the scattering cross sections are expressed as sums of two cross sections. The first accounts for specular point scattering. It is given by the physical optics cross sections for the filtered surface consisting of the large scale spectral components. The second accounts for Bragg Scattering. It is given by the perturbation cross section for the surface consisting of the small scale optical components that ride on the filtered surface.
