| Popis: | We study theoretically two-dimensionally periodic gratings of plasmonic strips on substrates which contain dielectric and plasmonic layers. The developed electrodynamic model is based on solving the vector integro-differential equation of diffraction by three-dimensional dielectric bodies by the Galerkin method. It is shown that at the resonant frequencies of the surface plasmon polariton, these structures absorb almost 100% of the energy of the incident radiation in a wide wavelength range. The use of nonmetal plasmonic materials makes it possible to create a wideband absorber of infrared waves. |
