The properties of X-ray vacuum-gap waveguides (WGs) with additional periodic structure on one of the reflecting walls are studied. Theoretical considerations, numerical simulations and experimental results confirm that the periodic structure imposes additional conditions on efficient propagation of the electromagnetic field along the WGs. The transmission… (More)

The effect of capture of X-ray beam into narrow submicron capillary was investigated with account for diffraction and decay of coherency by roughness scattering in transitional boundary layer. In contrast to well-known Andronov-Leontovich approach the losses do not vanish at zero gliding angle and scale proporpional to the first power of roughness amplitude… (More)

A new method for investigation of X-ray beam propagation in a rough narrow dielectrical waveguide is proposed on the basis of the numerical integration of the quazioptical equation. In calculations a model rough surface is used with the given distribution of hights of roughness and given correlation properties of the surface. The method is free from the… (More)
