Popis: An efficient method of numerical calculation of optical field distribution during propagation through generally anisotropic medium is proposed. The method is based on plane-wave representation of the vector field and is valid for nonparaxial case of highly focused laser beams and fully describe polarization effects. It allows to specify arbitrary distribution of intensity, phase and polarization at source plane and include both evanescent field and propagating modes into consideration. The computation algorithm is fast and easily parallelizable because conventional two-dimensional fast Fourier transform is used as a core.
