Diffraction of EM waves by perforated screen with finite width

摘要

A finite width screen with perfect conductivity and doubleperiodicity slots was considered. Let such the system be placed in anisotropic medium and be excited at an arbitrary angle by a planeelectromagnetic (EM) wave. We solved the problem of finding the fielddistribution in space and calculated its electromagnetic parameters. Theproblem was solved by means of the method of subsections. Resulting fromthe calculation, the dependence of the field transmission coefficient onthe different parameters and the field distribution inside the waveguidewere obtained. An analysis of the structure was also conducted
