Discrete Dipole approximation for Electron Energy Loss Spectroscopy

DDEELS, a Fortran code for simulating Electron Energy (low) Loss Spectroscopy (EELS) performed on irregular particles, has been developed by Nicolas GEUQUET and Luc HENRARD. It is based on the Discrete Dipole Approximation (DDA). The current version is DDEELS1.07alpha.

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)

v0.1: http://code.google.com/p/dda-si/

v0.2: https://github.com/dalerxli/dda-si

Functions from the Optical Tweezers Toolbox may be required: https://au.mathworks.com/matlabcentral/fileexchange/73541-ott-optical-tweezers-toolbox

The functions are for coordinate transformation, generating beam shape coefficients for arbitrary illumination, vector spherical wave functions etc.

This Fortran code by Yu You calculates the light scattering by an arbitrary particle, which has a non-unit electric permittivity as well a non-unit magnetic permeability. The code is based on the DDA code, DDSCAT 6.1, published by Draine and Flatau.
