Optical Interactions at Randomly Rough Surfaces
Abstract
This project is concerned with theoretical and experimental studies of the scattering of light from and its transmission through randomly rough surfaces. The most significant results obtained during the reporting period include the design of one-dimensional random surfaces that transmit light in a specified fashion; the demonstration that the scattering of light from the random surface of an amplifying (gain) medium increases the height of and narrows the enhanced backscattering peak; the prediction of multiple-scattering effects in the second harmonic generation of light in reflection from a clean random metal surface and in transmission through a rough metal film in the Kretchmann attenuated total reflection geometry; the theoretical study of the wavelength dependence of the reflectivity and total scattered energy when p-polarized light is scattered from a rough dielectric film deposited on a metallic substrate; the development of a new perturbation theory of rough surface scattering in which the small parameter is the dielectric contrast between the medium of incidence and the scattering medium; and the observation of spectral changes (Wolf shifts) obtained from a real image of a point source.
