FMPS (Fast Multi-Particle Scattering) Software
A variety of problems in applied physics and engineering require the solution of Maxwell's equations in complex micro-structured materials. FMPS combines high-order accurate integral equation methods with classical multiple scattering theory. It assumes only that the material consists of an isotropic background in which are dispersed a large number of micro- or nano-scale metallic or dielectric inclusions.

Ray-tracing rendering of 3D clusters of plasmonic nanoparticles with arbitrary positions, sizes, and orientations.
Brief description
The cda package implements the coupled-dipole approximation for electromagnetic scattering by sparse collections of subwavelength particles, with a particular focus on plasmonic nanoparticles in the visible regime. The interaction matrix, and the solution of the linear system of coupled-dipole equations are executed in C++ code for speed; convenient wrapper functions are provided at the R level to generate the particle clusters, calculate the extinction, scattering, and absorption of light by particles with linearly and circularly polarised light. Functions are also provided to calculate orientation-averaged circular dichroism, and display clusters of nanoparticles in three dimensions using OpenGL or povray.

The special issue of the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT) dedicated to Peter Waterman is now available.
Peter Waterman (1928–2012) is the creator of the T-matrix method and one of the pioneers of the theory of multiple scattering of electromagnetic and acoustic waves by multi-particle systems. To commemorate his landmark contributions to science and his profound and lasting impact on JQSRT, a special issue of JQSRT titled “Peter C. Waterman and his scientific legacy” has been published.

These Mathematica script files by Markus Selmke allow the extensive study of light-particle interaction phenomena enountered in coherent focused beam illumination of spherical (multilayered) scatterers, e.g. to compute the intensity collected by a detection microscope objective and recorded with a photo-diode, radiation pressures, the rel. photothermal signal, sopectra, Poynting vector flows and near fields among other things.
