The Multiple Sphere T Matrix Fortran-90 Code by Dan Mackowski.
MSTM is a package for calculating the electromagnetic scattering and absorption properties of systems of spheres.
The code is designed to run on distributed memory parallel platforms, and uses MPI instructions in conjunction with fortran-90.
Initial release date: 15 January 2011.
The DDA-SI toolbox for MATLAB:
1) Standard DDA for free space light scattering calculations
2) DDA with surface interaction (DDA-SI)
3) Discrete rotational symmetry-optimized DDA, T-matrix formulation (not include in release v0.1)
Download link for beta releases,
Functions from the Optical Tweezers Toolbox are also required:
The functions are for coordinate transformation, generating beam shape coefficients for arbitrary illumination, vector spherical wave functions etc.
