Abstract
We calculate the elements of the Stokes matrix for the scattering of light from a one-dimensional randomly rough metal surface in the general case when the plane of incidence is not perpendicular to the generators of the surface. By using Green's second integral identity one can obtain a system of four coupled integral equations for the components of the electric and magnetic fields parallel to the generators of the surface, and their normal derivatives, evaluated on the surface. The components of the scattered electric and magnetic fields are given in terms of integrals containing these four source functions. The system of four coupled integral equations is solved numerically for each of 2000 realizations of the surface profile function, and the results are used in calculating the elements of the Stokes matrix for the scattering geometry assumed. It is found that all elements of the Stokes matrix are nonzero, in contrast to the case when the plane of incidence is perpendicular to the generators of the one-dimensional surface. The results of this study provide complete information about the diffuse scattering properties of one-dimensional randomly rough metal surfaces.
