Scattering computations of non-spherical bodies with DDSCAT
The program DDSCAT from P. J. Flatau and B. W. Draine is based on the discrete dipole approximation.
At the IWT the program was expanded to compute the scattered light of ellipsoidal
layered bodies with an arbitrary index of refraction of the different layers.
In addition the excitation by a Gaussian beam was implemented. The field expansion of Davis was used up to the second order.
