Electromagnetic scattering of a uniaxial anisotropic sphere to a circular polarization wave

Electromagnetic scattering of a plane wave with circular polarization from a uniaxial anisotropic sphere with arbitrary primary optical axis is researched. The incident circular polarization wave is expanded in terms of the spherical vector wave functions (SVWF´s) in arbitrary primary optical axis coordinate and the expansion coefficients are derived by superposition of the expansion coefficients of two linear polarization waves. The electromagnetic fields in the uniaxial anisotropic sphere are proposed in the integrating forms of the spherical vector wave functions by introducing the Fourier transform. Utilizing the continuous tangential boundary conditions, both of the scattered and internal field coefficients are analytically derived. Scattering property of a uniaxial anisotropic sphere to a circular polarization wave is numerically analyzed and compared with that to a linear polarization wave. The effects of the anisotropy and different primary optical axis on scattering performance are also studied.
