Diffraction of electromagnetic wave by two-layer grating

Abstract

© 2015 I.E. Pleshchinskaya and N.B. Pleshchinskii. The electromagnetic wave diffraction problem by the two-layer grat- ing of thin conductive strips is reduced to an infinite set of linear alge- braic equations for the coefficients of the decomposition of the desired field by Floquet harmonics. The properties of quasi-periodic solutions of Maxwell equations are investigated. Method of integral-summatorial identities is used for the regularization of dual summatorial equations.
