Abstract

The paper presents an analysis of anisotropic grating in non-conical mounting. The grating is composed of the periodically alternating strips of anisotropic and isotropic material, so the relative permitivity tensor profile along the periodicity direction is piecewise-constant. The anisotropy is considered to be transversal and (in terms of magneto-optics) is induced by an external magnetic field in the direction perpendicular to the plane of incidence. The electromagnetic field in the grating region is expressed using Floquet modes and permitivity profile is expressed using Fourier expansion. Modal amplitudes are obtained from coupled-wave analysis performed in compact matrix form. The results are angular spectra of diffraction efficiencies for material and geometrical parameters. The numerical stability and convergence is discussed for every computed case.
