The theory of Anderson localization is used to study transmission enhancements in the diffusely transmitted light through a rough thin metal film. These transmission enhancements arise due to phase coherent effects associated with Anderson localization of surface polaritons and are manifested as a well-defined peak in the angular distribution of the intensity of the diffuse component of the transmitted light for light moving opposite to the specularly reflected beam.
The dependence of the widths and heights of the localization related transmission peak is investigated with computer programming and calculations by McGurn and Maradudin (1989). The peak is found to depend on the degree of surface roughness disorder and the dielectric constant of the media. We studied this transmission peak using the dielectric constants appropriate to silver, copper, and aluminum, finding the optimal condition for each material (silver, copper, and aluminum) under which the localization phenomena can be observed.
