Karazin Kharkiv National University popup.description2  During the third stage of this project the electrodynamic characteristics of the graphene gratings with brake of periodicity in the THz frequency range, graphene gratings embedded into a dielectric slab, multi-layer graphene gratings, and grating above a perfectly conducting plane were studied. The scattering and absorption characteristics, the excitation of the eigenwaves of dielectric waveguides were considered. The gratings under study support variety of resonances: plasmon resonances, grating-mode resonances, resonances near the Rayleigh anomalies, resonances of the multi-layer structure. The mathematical models of a single-layer finite and infinite gratings embedded into dielectric slab, gratings with brake of periodicity such as semi-infinite grating and infinite grating with an arbitrary gap between two neighboring strips, multi-layer gratings where every layer consist of a graphene grating embedded into dielectric slab, and infinite grating situated above the perfectly conducting plane were built. All models are based on the combination of the methods, method of singular integral equations and operator method. Such an approach allowed to decrease significantly the computation time and allowed us to consider gratings with much larger number of strips and layers. The convergence is based on the theorems.
