Diffraction of Light from Randomly Rough Surfaces
Abstract
A combined theoretical and experimental investigation of the scattering of light from randomly rough metallic, dielectric, and perfectly conducting surfaces has been carried out. A major goal of this research program has been an increased understanding of the phenomenon of the enhanced backscattering of light from such surfaces, viz. the narrow peak in the angular distribution of the intensity of the incoherent component of the scattered light in the retroreflection (backscattering) direction. At the same time, a new effect has been predicted and observed in the transmission of light through a thin metal film with random surfaces. This is enhanced transmission, viz. a narrow peak in the angular distribution of the intensity of the incoherent component of the transmitted light in the antispecular direction. Both enhanced backscattering and enhanced transmission are examples of the weak localization of classical (electromagnetic) waves due to their interaction with a random medium.
