Library with the filtered Green's tensor by Nicolas Piller.The filtered Green's tensor is a modified Green's tensor developed to improve the accuracy of the coupled-dipole approximation (CDA) or discrete-dipole approximation (DDA).

Based on DDSCAT DDA_field adds the following additional capabilities to DDSCAT: (1) treatment of particles in solvent, (2) calculation of near-field properties such as local electric field, including the calculation of near-field properties on a grid that is different from the DDA grid, (3) periodic boundary conditions, (4) consideration of many other shapes of particles, and of more than one particle in the simulation box.

ADDA is a C software package to calculate scattering and absorption of electromagnetic waves by particles of arbitrary shape and composition using the discrete dipole approximation (DDA). The particles can be located in a homogeneous medium or near a plane substrate; emission (decay-rate) enhancement of point emitters can also be calculated. The main feature of ADDA is the ability to run on a multiprocessor system or multicore processors (parallelizing a single DDA simulation). It can also employ modern GPUs to accelerate computations. ADDA is intended to be a versatile tool, suitable for a wide variety of applications ranging from interstellar dust and atmospheric aerosols to metallic nanoparticles and biological cells. Its applicability is limited only by available computer resources.

This software is available under GNU GPL 3. Full source code, Windows binaries, and extensive documentation are available.
