Dichroism and Birefringence in X-Ray Spectra of Forbidden Reflections

An approach employing the transmittance matrix has been implemented to calculate the intensity of Bragg reflections in resonant X-ray diffraction. This enables the inclusion of anisotropic effects that lead to a change in the polarization of radiation during propagation. Using the example of processing the spectra of forbidden reflections in an iron orthoborate crystal, performed with a program based on this approach, an improvement in the agreement between calculated results and experimental data is demonstrated in comparison with standard methods.
