RESUMO

The analysis of anisotropic dielectric gratings was done by considering an uniaxial anisotropy. The dichroic characteristics were studied in the millimeter wave band of anisotropic dielectric gratings using a Rigorous Modal Theory. The numerical results are presented as functions of parameters of sinosoidally and step varying dielectric constants, as well as of wave polarizations of TE or TM type. The anisotropy effect is studied by varying the square of the anisotropy ratio of the material. The numerical results show how this variation affects the resonant profile of these gratings and the advantages ofusing anisotropic dielectric gratings in filters
