EM wave scattering from a slightly rough surface of an anisotropic medium

Summary form only given. The theoretical analysis of the interaction of EM waves with anisotropic media is interesting for applications such as remote sensing, nondestructive testing and microelectronics. We consider the problem of two media, one gyrotropic and one isotropic, separated by a boundary covered by small-height and gently sloping roughness. The axis of symmetry of the gyrotropic medium is perpendicular to the unperturbed boundary. The model we use of the gyrotropic medium can describe a magneto-active plasma, a ferrite in an external static magnetic field and certain artificial dielectrics. The model of a weakly rough surface can be used to describe the lower boundary of the ionosphere and non-ideally processed surfaces of manufactured objects. Simpler scattering problems involving isotropic media only have been extensively treated in the past. This report extends the previous research to account for anisotropy of an underlying medium. We present an analytic solution for the fluctuating field using a small perturbation approach, and analyze the effect of anisotropy on the scattering pattern of random roughness.
