Polarimetric scattering and transmitting of the Stokes vector from a layer of chiral small spheroids

Abstract

To measure fully polarimetric scattering from random chiral small spheroids, the 2 × 2 dimensional (2 × 2-D) complex scattering amplitude matrix of randomly oriented, chiral small spheroid is derived. Polarimetric scattering from a bounded layer of non-uniformly oriented, chirally-active small spheroids in the Mueller matrix solution is obtained. Co-polarized and cross-polarized backscattering and polarization degree for any polarized incidence (χ, ψ) are numerically calculated. Transmitting of coherent Stokes parameters through the layer are also discussed. Either non-uniform orientation or chirality can yield non-diagonal extinction matrix {ie130-1} and full eigenmatrix Ē due to the fact of forward depolarized-scattering functions 〈f ^vh ₀ 〉, 〈f ^hv ₀ 〉 ≠ 0. Comparisons of fully polarimetric scattering from the chiral and achiral particulate media demonstrate the chirality effect on wave scattering and transmitting.
