This FORTRAN code for spherical scatterers with a complex permittivity and a complex permeability is listed in
Merril E. Milham, Electromagnetic scattering by magnetic spheres: theory and algorithms, Edgewood Research Development and Engineering Center, ERDEC-TR-207, Oct. 1994, ADA289798.
The size parameter may be as large as 23000.
This set of Matlab programs by Tami Bond calculates absorption, scattering and backscattering for spherical, coated or uncoated particles of lognormal or measured size distributions. There is also a utility to do several runs from parameters given in an Excel worksheet.
