Gaussian beam propagation through a biaxial anisotropic circular cylinder

Abstract

Based on the electromagnetic field expansions over appropriate cylindrical vector wave functions, the scattering features of a Gaussian beam by a biaxial anisotropic circular cylinder are analyzed. The unknown expansion coefficients are determined from a system of linear equations derived by using continuous boundary conditions. For a TE and TM polarized Gaussian beam with different propagation directions, the normalized near-surface and internal field intensity distributions are evaluated. The propagation properties are compared and discussed briefly.
