Abstract
The theoretical model of the evanescent waves coupling with dielectric and metallic strip gratings is described. The interaction of electromagnetic field with lamellar periodic structures and their diffraction properties are determined by coupled wave method implemented as the Fourier modal method. The simulations of the ellipsometric response under internal reflection for different geometrical and material configurations are presented. The attention is concentrated on the study of coupling strength influence, effects connected with stripes geometry, and, with absorption in metallic elements of grating.
