Special cases of low symmetry absorbing crystals

Peculiarities of eigenwaves in absorbing low symmetry crystals were investigated. As it was shown by F.I. Fedorov and A.M. Goncharenko, there are substantial differences in monoclinic crystals. Six variants of existence of optical axes in such crystals were considered in details. Changes in ellipticity of eigenwaves were investigated. Substantial difference between these cases is shown. This difference can be clearly seen on dependencies of ellipticity and intensity of the transmitted light from the angle of incidence in the cases when the incident light has right or left circular polarization.
