Laws of the behavior of the angular characteristics of light scattering by crystalline particles in the weak-anisotropy approximation

Stokes parameters for light scattering from a Faraday-active sphere

“…We observe that off-diagonal F-elements such as F 1 12 and F 1 41 , are generally more important in the angle region of 140 − 170 • , and increase with the size parameter. In this region, these Stokes parameters seem to be very sensitive to anisotropy as also found from studies of Stokes parameters of quartz particles [16].…”

“…An alternative derivation consists to take the limit θ → 0 so that R 1 = R 2 or θ → π so that R 1 = −R 2 in Eqs. (15)(16)(17)(18). This yields,…”

“…We can write all the expressions above in a very compact way using the basis of the Pauli matrices [16]…”
