Abstract

A theory for electromagnetic scattering from a slightly rough surface is developed that is based on application of an effective boundary condition. The theory generalizes previous approaches that apply only to the infinite dielectric constant (/spl epsi//spl rarr//spl infin/) limit to cases of finite but large /spl epsi/. Also, the theory yields the known results by J. Wright. In a particularly important case of scattering from the ocean, the backscatter cross-section is dramatically different from that calculated for /spl epsi//spl rarr//spl infin/ over a wide range of incident angles, for both vertical and horizontal polarization.
