Scattering of plane electromagnetic wave by a circular cylinder near a uniaxial anisotropic plane interface

Abstract

For an incident plane electromagnetic wave, its scattering by an infinitely long circular cylinder near a plane interface between free space and a uniaxial anisotropic medium is investigated. The electromagnetic fields within different regions are expressed as expansions in terms of appropriate rectangular or cylindrical vector wave functions, and the unknown expansion coefficients are determined by the continuous boundary conditions. To examine the coupling scattering effects involving the circular cylinder and the plane interface, the transformations of rectangular and cylindrical vector wave functions are applied. Normalized scattering widths and polarization states of the scattered fields are calculated, and the scattering features are discussed briefly.
