Abstract

A finite width screen with perfect conductivity and double periodicity slots was considered. Let such the system be placed in an isotropic medium and be excited at an arbitrary angle by a plane electromagnetic (EM) wave. We solved the problem of finding the field distribution in space and calculated its electromagnetic parameters. The problem was solved by means of the method of subsections. Resulting from the calculation, the dependence of the field transmission coefficient on the different parameters and the field distribution inside the waveguide were obtained. An analysis of the structure was also conducted
