(Cipher: «Старт-5») Head Petro M. Melezhyk, Доктор фізико-математичних наук Registration Date 26-02-2020 Organization O. Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description1 Development of new theoretical and experimental methods of electrodynamical modeling of laws and phenomena inherent in gigahertz and terahertz electromagnetic wave diffraction, propagation, absorption, scattering, transformation, and channeling taking place in open resonant structures and stratified nonlinear dielectric layers, diagram-forming thin graphene-like coats and micro- and nanoantennas with complex-shape patches, in open double-comb resonators with strip electron flows and in leaking-wave resonators; in spherical-mirror open resonators with nanoparticles, in metamaterials, in nonlinear media and superdimensional waveguide structures; in open resonant systems with spatially developed electron beams and 3-D frequency-selective structures, with making on this basis laboratory models of vacuum electromagnetic wave radiation sources and general-purpose devices in the gigahertz and terahertz wave regions. popup.nrat_date 2024-12-10 Close
