Point Focusing of Two-Dimensional δ-Shaped X-Ray Wave Diffracted on a Crystalline Plate Using an Elliptical Zone Plate

The possibility of the two-dimensional focusing of hard X-rays diffracted on an ideal crystalline plate is considered. It is assumed that the Laue geometry of diffraction takes place, and the wave incident on the crystalline plate is delta-shaped in two mutually perpendicular directions in the plane tangential to the wave vector. A Fresnel zone plate with elliptical zones is used as a focusing device. Numerical simulation of the focusing is carried out.
