Abstract

Based on the spherical vector wave functions, we research the scattering of a homogeneous chiral sphere to a plane wave. The expansion coefficients of scattered fields and internal fields are obtained through the boundary condition at the sphere interface. The logarithmic derivatives of Ricatti-Bessel functions are introduced in order to avoid the numerical overflow of high-order terms or larger argument spherical Bessel function and the problem of the accumulative error in the matrix calculation. Thus, the scattering characteristics of a chiral sphere with larger size parameter can be studied numerically. Moreover, the influence of chiral parameter on the polarization properties is also numerically analyzed.
