Abstract
Using perturbation theory, we have investigated the electromagnetic field reflected by a two-layer medium with rough boundaries. To first order in perturbation theory with respect to the asperities on the boundaries, we consider the scattering fading effect. To a second approximation, we have obtained analytical expressions for the perturbations of the mean field reflected and transmitted into the medium, and also analytical expressions for the second moment of the field with orthogonal polarization scattered in the plane of incidence. We have investigated the dependences of the second moment of the field on the character of the asperity spectrum, the frequency of the radiation, and the layer thickness.
