摘要：
The propagation of X-rays in one-dimensionally confined waveguides is analyzed by means of finite-difference calculations based on the parabolic wave equation. We compare the numerical results to an analytical approach and investigate the transmission and coherence properties of a waveguide depending on its length and the number of guided modes corresponding to the guiding layer thickness.
