Backscattering enhancement from a dielectric surface

Abstract
Using the unitary and reciprocal theory of Brown et al. [Surf. Sci. 136, 381 (1984)], we calculated numerically the differential reflection coefficient for the scattering of an electromagnetic wave from a weakly corrugated, randomly rough dielectric surface. For a one-dimensional surface we did not see enhanced backscattering except when the contribution from single scattering processes was subtracted. For a two-dimensional surface we clearly saw enhanced backscattering in the cross-polarized scattering.
