Abstract

Two improvements are made in modeling polarimetric scattering by ensembles of particles. (1) We propagate the complex scattering matrix instead of the phase function. This allows us to calculate the phase and polarization properties of an entire cloud of particles. Radiation transfer models deal only with the intensity of the scattered light. The advantage is that the new model can deal with situations in which the light is scattered coherently. (2) Monte Carlo methods require calculation of scattering at all angles for each successive particle. The new model requires the calculation of only one scattering angle. This allows for use of sophisticated electromagnetic scattering models such as the Discrete Dipole Approximation, WKB or Digitized Green Function models. The advantage is that we can treat particles of arbitrary morphology more accurately.
