(1) DELPI 1.1: Diffusion Electromagnétique de la Lumière par des Particules Isolées

Electromagnetic scattering of light by isolated particles (but in French...)

Description (in brief):

This windows-based software allows calculating the extinction cross sections and scattering diagrams of homogeneous, coated and multilayered particles: spheres and cylinders (with a right cross section) illuminated by a plane wave (Lorenz-Mie Theory). In fact, as a demonstration software for students all features connected to the beam shape (Generalized Lorenz-Mie theory) or inclusions (Monte carlo method) are deactivated. The software is in french but I guess any english speaker can use it without difficulty.

Main features of the software:

Spherical and cylindrical particles: homogeneous, coated and multilayered (demo limited to 50 layers and to moderated size parameters).
Scattering diagrams
Intensity at a given angle versus the particle diameter
Extinction, Scattering and absorption efficiencies
Export: graphs and raw calculations
