Light scattering by randomly rough isotropic dielectric surfaces (original) (raw)

2000, Journal of Modern …

An experimental investigation of the angular distribution of the light scattered by randomly rough, two-dimensional, isotropic dielectric surfaces is presented. T he surfaces, whose pro® les constitute good approximations to Gaussian random processes with Gaussian correlation functions, are fabricated in a photoresist and characterized by means of a mechanical pro® lometer. T he substrates employed in the fabrication of the samples consist of thick parallel plates of ® lter glass that absorb the incident light and whose refractive index is close to that of the photoresist. T his allows us to approximate experimentally a situation in which the light is scattered by a randomly rough interface between two semi-in® nite dielectric media, illuminated from the air side. T he results display features that can be attributed to multiple scattering. In particular, signi® cant amounts of cross-polarized scattered light, as well as an enhanced backscattering peak, were observed in the scattering measurements.
