title: Backscattering enhancement of an electromagnetic wave scattered by two-dimensional rough layers.
abstract: The problem of an electromagnetic wave scattered by a slab with two rough boundaries is solved by the small-perturbation method under the Rayleigh hypothesis. To obtain the perturbative development, we use a systematic procedure that involves integral equations called the reduced Rayleigh equations. Then we show for a dielectric slab deposited on a silver film that the backscattering enhancement can be produced by guided waves that interact with the two rough surfaces.
