Paper Abstract

We report on our work about the electromagnetic theory of gratings made with anisotropic materials. We describe briefly and give the fields of application of both differential and integral methods. At the present time, a computer program based on the integral method works for an arbitrary uncoated dielectric anisotropic grating, the surface of which is given by y=f(x), provided that the principal axes of the permittivity matrix be the ones used to describe the geometry of the structure. The differential method, which is very flexible and easy to implement, allows us to deal with a great variety of problems. A computer program has been written which treats the problem of an anisotropic substrate covered with an anisotropic layer, and does not require any restrictive condition on the permittivity matrices. Unfortunately, the numerical difficulties which appear especially for deep and lossy gratings are not yet completely removed.
