Registration Date 15-02-2022 Organization O. Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description2 The object of research is the processes of diffraction and interaction of electromagnetic fields with resonant and dispersion waveguide transmission lines, natural and artificial media (including double negative and 1-D and 2-D photonic crystals and the processes of wave radiation in diffraction type antennas. The purpose of the work - to study the physics of transient and steady processes of propagation, compression and radiation of electromagnetic pulses; creation of rigorous mathematical models describing waves in artificial media (double negative, photonic crystals, etc.) and in waveguide transmission lines with group velocity dispersion, which would be suitable for the construction of microwave pulse compressors; creation and thorough study of laboratory models of diffraction radiation antennas for various applications; modeling and experimental study of the action and interaction of electromagnetic radiation with media of organic and inorganic origin, as well as the study of changes in the physiological state of cells under the action of electromagnetic waves and biologically active substances. theoretical and experimental study of oscillations and waves of the electromagnetic field in electrodynamic structures (open resonators with metal mirrors, dielectric resonators, anisotropic dielectric layers, layered superconductors, planar photonic crystals, magnetophotonic crystals), which are of great interest to Research methods - method of wave front rotation, method of incomplete separation of variables, method of integral transformations, method of exact absorbing conditions, method of finite differences in time domain, methods of computational electrodynamics, methods of computer modeling of electrodynamic systems, experimental methods of radiophysics and radio measurements. modeling and computational and field experiments.
