Implementation of various Bessel beams in the framework of the discrete dipole approximation

Given by Stefania Glukhova at METANANO-2020 conference on 17.09.2020. Abstract: In this work we generalize the classical framework of Mueller (or amplitude) scattering matrices for the Bessel beams (BBs). For that we extend the rotation relations of BBs (considering 'vortex' additional phase factor) for an arbitrary angle, which are useful for solving the scattering problem in a rotated coordinate system. Thus, we rework the existing classification of the BBs and their polarizations with the focus on rotation relations between them. We have already implemented all BB types with arbitrary polarizations/rotations in a separate branch of ADDA, and are working on testing the code. As a result, it should be trivial for anyone to simulate the scattering of Bessel beams by arbitrary inhomogeneous particles, including randomly orientated ones.
