Abstract
Scattering from a rough interface between a simple isotropic medium and a uniaxial lossy medium is analyzed using the first-order perturbation theory (PT) and the small slope approximation (SSA). We consider a more generic uniaxial lossy medium exhibiting electric and magnetic anisotropy and an arbitrarily oriented optic axis. Scattering from the rough interface of such a medium is analyzed by assuming both deterministic sinusoidal function and a Gaussian distribution for the surface roughness. We also study the coherent and incoherent intensities employing both the PT and the SSA. The impact of surface roughness, anisotropy and material losses on scattering characteristics is examined. We show that the parameters describing the surface roughness, i.e., height, period, and slope may add significant contribution to the electromagnetic scattering from the anisotropic interface.
