Paper Abstract

A new analytical solution for the local optical characteristics (extinction, light pressure, and absorption coefficients, asymmetry parameter of a phase function) of spherical polydispersions with comparatively large particles are derived. The geometrical optics (GO) approximation is used to solve the problem. To improve the accuracy of the GO approximation the edge effects were taken into account. A comparison with the Mie theory data shows a fairly satisfactory accuracy of our analytic formulas.
