The Null-field Method with Discrete Sources is an extension of the Null-field Method (also called T-Matrix Method) to compute light scattering by arbitrarily shaped dielectric particles. The Fortran code is inculded on CD with the book:

ScattPy
ScattPy is an open source Python package for light scattering simulations. Its goal is to provide an easy-to-use and flexible modern framework for the numerical solving of the diffraction problems with various kinds of particles. ScattPy includes the separation of variables (SVM), extended boundary condition (EBCM) and point matching (PMM) methods.

Fortran code for Electromagnetic Scattering by Spheroids by Peter G. Martin.
MMP FORTRAN code for electromagnetics simulation available on disk in
Christian Hafner, Lars Bomholt, The 3D Electromagnetic Wave Simulator, Wiley, Chichester 1993.
The book is out of print, but the tex-file and an executable code of 3D MMP compiled for Windows NT is available from Christian Hafner's server, ETH Zürich.
This code may be used for scattering by nonspherical nonsymmetrical arbitary 3D bodies. It has been applied to spheres in a Gaussian beam, spheroids, plates, cubes, finite cylinders, rain drops, spheres having multiple inclusions, clusters of spheres, spheroids and plates.

For scattering by 2D bodies e.g cylinder available on disk in
Christian Hafner, 2-D MMP: Two Dimensional Multiple Multipole Analysis Software and User´s Manual, Artech House, Boston 1990.
The book is out of print but book and code are available from Christian Hafner's server.
This code calculates the extinction, scattering and absorption efficiency factors for prolate or oblate homogeneous spheroids. The separation of variables method (SVM) and an original scheme of solution of the light scattering problem are used.
A demo version of this programme is available from the Wiley site and the MaX-1 ETHZ site.
This is a new 2-D version of the MMP technique with a wide range of application including statics, scattering, gratings, antennae, guided waves, resonators and discontinuities.
