Transmission of shaped beam through a rotationally uniaxial anisotropic sphere

Abstract

We proposed a semi-analytical solution to the arbitrarily shaped beam scattering by a rotationally uniaxial anisotropic sphere. The scattered and internal fields are expanded in terms of appropr- iate spherical vector wave functions, and the unknown expansion coefficients are determined by virtue of the boundary conditions and the method of moments procedure. For incidence of a Gaussian beam, zero-order Bessel beam and Hertzian electric dipole radiation, numerical results are given for the normalized internal and near-surface field intensity distributions, and then their properties are discussed concisely.
