Study of Electromagnetic Wave Scattering from Characterized Rough Surfaces

Abstract

In our experimental and theoretical research during our ARO grant, we have studied the optical scattering properties of rough conducting surfaces that have structure comparable to or slightly greater than the illumination wavelength. We theoretically and experimentally studied the diffuse scatter for surfaces with one-dimensional roughness, where we have seen backscattering enhancement and strong polarization effects. In the angular correlation functions associated with the scattered light, we clearly see the coherent effects that give rise to backscattering enhancement. Further experimental studies have considered backscattering enhancement from a surface with two dimensional roughness, and we have theoretically investigated the effects of finite stylus width in the contact profilometer methods that we have used in our experiments.
