The Enhanced Backscattering of Light from Random Surfaces and Related Phenomena.

Abstract

The scattering of electromagnetic waves from, and their transmission through, randomly rough surfaces has been studied theoretically and experimentally. The first rigorous, computer simulation, results for the in-plane and out-of-plane, co- and cross-polarized scattering of electromagnetic waves from two-dimensional random metal surfaces have been obtained. It has been shown theoretically that the angular distribution of the intensity of the diffuse component of the electromagnetic waves scattered from, or transmitted through, a thin dielectric or metallic film that supports two or more guided or surface waves displays satellite peaks in addition to the enhanced backscattering and enhanced transmission peaks. New features (dips) have been predicted to occur at special scattering angles in the scattering of electromagnetic waves from one-dimensional random metal surfaces that are periodic on average rather than planar. Experimental studies have confirmed the existence of enhanced backscattering of electromagnetic waves from one-dimensional, deterministic, metal and dielectric surfaces. The limits of validity of various perturbation theories for the coherent scattering of p- and s-polarized electromagnetic waves from dielectric and metallic surfaces have been determined through simulation and experimental studies.
