Abstract :
A numerical approach based on the finite element method is described for the analysis of general three-dimensional, conical diffraction by arbitrarily profiled gratings. In order to show the validity and usefulness of this approach, the calculated conical diffraction efficiencies of groove-type dielectric gratings are presented
