Bragg–Laue X-ray dynamical diffraction on perfect and deformed lateral crystalline structures

The two-dimensional dynamical theory of X-ray Bragg–Laue diffraction has been developed for deformed lateral crystalline structures having a rectangular cross section. This approach allows one to calculate rocking curves as well as reciprocal space maps for both the transmitted and reflected wavefields. The approach can be used in coherent diffraction imaging to simulate far-field diffraction patterns produced by relatively large deformed crystals.
