Abstract
Scattering of electromagnetic waves from a dielectric slab loaded with a periodic array of perfectly conducting strips is analyzed by a mode-matching technique. The variation of energy of significant scattered modes with various structure parameters is presented for both principal polarizations of the incident wave. The convergence and accuracy of the numerical method is evaluated. Further numerical results are obtained to show the effects of various parameters on the distribution of power in various propagating modes. The results show the usefulness of these structures as reflection-type gratings, polarizers, and filters.Keywords
