Scattering of an electromagnetic wave by a fractal cluster of monosized spheres, using the mean field approximation introduced by Botet, Pascal Rannou, Cabane in 1997 (Botet 1997): Botet et al, APPL. OPT. 36, 33 (1997) 8791-8797.
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.

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.

Mie theory and a cluster T-matrix algorithm, coded with Matlab (6.3) by Sylvain Lecler, are available in a compressed version here. These programmes have a graphic user interface and descriptive documents.
