Paper Abstract

We analyze the electromagnetic wave scattering problem from multilayer-coated Fourier grating for a general angle of incidence and arbitrary polarization. This analysis is treated in quasi-two-dimensional problem with the scalar wave function where the incident wave vector is not perpendicular to the ruling direction of the gratings. The analytically procedure is applied to T-matrix method with R-matrix propagation algorithm. This formulation can be calculated in the closed-form expressions because R-matrix propagation algorithm is used avoiding a singularity in matrix elements for the evanescent mode. Numerical examples are also presented for diffraction efficiencies versus incident and azimuth angle.
