   A general approach to study the totality of polarization angles for single-layer absorbing systems is developed. This approach is easily extendable to multilayer media. It is demonstrated that the main features in the behavior of PSI and DELTA polarization angles which show up in the angles of polarization and during transition from one DELTA step type to another remain also in the case of absorbing media.
