Electromagnetic characteristics of 3D photonic crystals are obtained, a phenomenon of negative refraction, effects of ultra-high resolution, processes of electromagnetic radiation self-collimation in these crystals are studied, a diffraction of light on planar metal-dielectric periodic structures and an interaction of the local source with periodic nanostructures are investigated. Electromagnetic characteristics of microstrip arrays and planar screens of finite thickness with holes are investigated, surface Green tensors for microstrip antennas are obtained, an algorithm for the study of electromagnetic characteristics of the substrate microstrip grating in the form of electromagnetic crystal are developed , frequency-selective and polarization properties of the planar screens of finite thickness with coaxial-sector holes are investigated and characteristics of electromagnetic fields at scattering of wave beams on planar screens with waveguide channels of a rectangular cross section are obtained. Software for radar signal processing and imaging of the lunar surface is developed. Product Description popup.authors Антоненко Ю.В. Віділ М.Ю. Воробьов С.М. Грибовський О.В. Кочин В.М.
