Scattering Cross Sections for Two Dimensional Rough Surfaces with Different Correlation Lengths

摘要

To obtain the scattering cross sections for rough surfaces with different roughness scales, a full wave approach (based on the complete expansion of the electromagnetic fields and the imposition of exact boundary conditions) has been used to convert Maxwell's equations in rigorous sets of generalized telegraphists' equations for the forward and backward scattered wave amplitudes. The full wave approach accounts for specular point scattering as well as diffuse scattering in a self-consistent unified manner. The single scatter approximations of the rigorous full wave solutions indicate that the enhanced like and cross polarized backscatter is a first order effect. Reprints. (jhd)
