Abstract

It is shown that the presence of an arbitrary body buried near a dielectric highly rough random surface produces a remarkable enhanced backscattering peak in the angular distribution of mean scattered intensity. This is in contrast with the distribution that the dielectric rough surface yields in the absence of the body. In order for the peak to appear, the surface must be very rough and the contrast between the dielectric constants of the body and the medium in which it is immersed must be 2 at least. We illustrate the results with a two-dimensional (2-D) calculation of a cylinder in front of a 2-D rough profile immersed in a dielectric medium. Different cases have been addressed in order to investigate the dependence of the backscattering enhancement on several physical parameters such as the width of the incident beam; the size, position, and optical constant of the buried cylinder; and the surface correlation function, as well as the difficult task of performing averages that resemble the ideal ensemble averaging of the rough surface in this system.
