Methods for modeling and computing problems of diffraction on domain walls and vertical Bloch lines of uniax:ial ferromagnetics with cylindrical magnetic domains are analyzed. The three-dimensional boundary-value problem of diffraction of a plane electromagnetic wave on the domain walls and the vertical Bloch lines in ferrite-garnets is considered. In accordance with the method of anisotropic dark-field observation, the solution is sought in the form of the superposition of nondiffracted and magneto-optical parts. The results obtained and experimental data are compared.
