    "abstract": "In this work the interaction of electromagnetic field with quasi-periodic\nmedia has been scrutinized. We have obtained the formula for a distorted medium\npolarizability tenzor in the X-ray frequency band. Also there have been\nobtained the X-rays dynamic diffraction equations for media with arbitrary\nsmooth distortion. For these equations the Takagi-Tuipin equations are obtained\nas a particular case. We have got a very simple formula for the coefficient of\nX-ray reflaction on the bent Bragg mirror. We have scrutinized the example of\ncalculating the X-rays reflaction and focusing by the bent Bragg mirror. Also\nin this work one could find the rezults of calculating the reflected X-rays\ncaustics form. It is shown that there exists a possibility of linear dimensions\nof the X-rays focusing area having typical values of 10^-7 cm.",
