A spectral domain method combined with the sampling theorem is described for evaluation of induced surface current densities concerning an infinite plane metallic grating loaded with a dielectric layer. Two different polarizations, TM and TE excitations, are treated here. Edge condition is analytically considered, and final results show a good convergence.
