Transmission of an X-ray beam through a two-dimensional photonic crystal and the Talbot effect

What is it about?

Results of computer simulations of the transmission of an X-ray beam through a two-dimensional photonic crystal as well as the propagation of an X-ray beam in free space behind the photonic crystal are reported. The photonic crystal consists of a square lattice of silicon cylinders of diameter 0.5 µm. The amount of matter in the path of the X-ray beam rapidly decreases at the sides of the cylinder projections. Therefore the transmission is localized near the boundaries, and appears like a channeling effect. The iterative method of computer simulations is applied. A peculiarity in the intensity distribution inside the Talbot period zT in free space was found

Why is it important?

We got new knowledge about interaction of x rays with matter and found properties of new device for a modification of synchrotron beam
