(a) Scheme of X-ray diffraction in a cylindrical crystal in the reciprocal (left) and direct space. (b) The two-dimensional network for calculating the diffracted S and the transmitted T X-ray waves in the direction of the wavevectors kh and k0, respectively. Red nodes indicate the passage of X-rays in vacuum (the optical path difference between the network nodes is shown in the inset); green nodes correspond to the crystalline space in which X-ray diffraction occurs. Schematic representations of the dynamical (c) and kinematical (d) X-ray diffraction. |
