Abstract

Based on the rainbow of isotropic theory, the rainbow of chiral sphere are discussed numerically and exam the correctness degenerating to isotropic. Geometric reflection and refraction path diagram of the light in the chiral media sphere surface is given, and the extrema scattering angle formulas in the co-polarization and cross-polarization are deduced in detailed. The influence to rainbow angle is numerical analyzed with different chiral parameter radius of particle refractive index, respectively.
