Abstract

A rigorous integral equation formulation in conjunction with Green´s function theory is used to analyze the scattering phenomena by a periodic dielectric grating slab waveguide. Such a structure is mainly utilized to obtain a frequency selective surface, finding applications both in the microwave and the optical region. The grating is modeled as a periodic layer with grooves regular plane regions. The advantages of the developed method with respect to already established ones are discussed. The dependence of the waveguide´s reflectance and transmission from the grooves characteristics is investigated.
