摘要

This contribution concentrates on modeling of diffraction processes in surfaces-relief gratings, occurring particularly within resonant regions. First, the characterization of mechanisms and diffraction processes is briefly presented, together with the regions with typical diffraction regimes, types of volume phase synchronism and their periodicity. The resonant regions are characterized by strong energy interchange processes (since new diffraction orders start to become propagating), the diffraction efficiency behavior within such a region is described and interpreted. Two main subregions of resonant regions are found: (1) the region with effective behavior "mound" and (2) the region with resonant coupling. The conditions for the existence of the first subregion are presented and explained. [References: 11]
