Abstract

Derived from the light scattering by a radially anisotropic sphere, unusual scattering behavior is exhibited, which breaks the Rayleigh law (scattering efficiency Qscaq4 as q0, where q is the size parameter). Under certain conditions, we demonstrate an asymptotical relation between Qsca and q, i.e., Qsca=Fq8, which is not realizable for isotropic particles in Rayleigh regime. Moreover, suitable adjustment of the anisotropic parameters can further suppress the coefficient F, resulting in enhanced transparency of the anisotropic particle.
