BUFF-EM is based on the volume-integral technique and can can handle objects with anisotropic and/or continuously spatially varying dielectric permittivity.


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)

Download link for beta releases,

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

v0.2: http://diogenes.iwt.uni-bremen.de/vt/laser/codes/DDA_toolbox_v0.2.zip

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.
