Paper Abstract

The enhanced transmission effect, manifested as a narrow peak in the angular distribution of the intensity of diffuse scattered light in the antispecular direction, has been experimentally investigated when a p-polarized laser beam passes through a metal film deposited on a piece of glass substrate. This peak is an analogue of enhanced backscattering in the transmission of light through a randomly rough metal surface. A fully automatic bidirectional reflectometer was used to measure the enhanced transmission of gold and silver surfaces under illumination of He-Ne laser. The results are compared with a recent perturbation theory of the localization of surface polaritons.
