Diffraction by the semi-infinite knife-type grating of material strips

Diffraction of the H - polarized electromagnetic wave by semi-infinite knife-type grating which consists of material strips is considered. The operator method is used for solution. As a result nonlinear operator equation relatively unknown reflection operator is obtained. The convergence of solution of nonlinear operator equation for the gratings of perfectly electric conductor strips and material strips is discussed. The results for near and far field are represented.
