Scattering program for a bisphere.

This program is based on the derivation given in Videen, Ngo and Hart, Opt. Comm 125, p. 275 (1996) except the refractive indices of the spheres are not restricted to being perfectly conducting.

NAOPC (Numerical Averaging of Optical Properties of Clusters) is a software package to obtain optical properties (cross sections, phase matrix) of a group of spherical particles based on the numerical orientation averaging using Quasi-Monte-Carlo method is given. The calculation for a fixed orientation is based on the T-matrix method. By Yasuhiko Okada.

A superposition T-matrix code for computing electromagnetic scattering by randomly oriented two-sphere clusters with touching or separated components is available from Michael Mishchenko.

The code uses an analytical method for averaging over cluster orientations and is significantly faster than codes employing numerical integrations over orientation angles. The cluster components can be identical or can have different sizes and/or refractive indices. The component sphere size parameter can exceed 40.
