Empirical Expression of Phase Function for Non-Spherical Particles
Chen CHENG, Qing-shan XU, and Lin ZHU
In electromagnetic radiative transfer calculations, the accuracy and the computation timeare usually determined by the representation of scattering phase function. Accurate calculations are time consuming even for non-spherical particles. In order to get a better fit to exact calculations and simulate the backward-scat
