Karazin Kharkiv National University popup.description2  The study of frequency-selective surfaces of planar formation of inductive type is presented. The dependencies of the transmission, reflection distribution of the electromagnetic field in such structures vs dielectric set of substrates, and vs the dielectric constant are studied. Wood’s type resonances in all-ferrodielectric periodic metasurface have been investigated experimentally and theoretically. The lattice resonance of the metasurface and the spatial distribution of the normalized transmitted cross-polarized component were experimentally detected. The cross-polarized transmission factor has maximum values near the resonant frequency. Theoretical studies of a shielded two-layer dielectric of finite thickness, the layers of which are separated by a layer of graphene. Green surface tensors are obtained. Theoretical and experimental results of research of electrodynamic characteristics of antennas on the basis of a microstrip disk with a fractal topology which is excited by an auxiliary concentric ring are presented. The influence of changing the topology of the excitation element on the spectral characteristics and mathing of the structure with external circuits is investigated. The results of the research can be found in experimental studies of functional elements of microwave and K bands. They can be useful for the training of highly skilled personnel, laboratory and graduate work. Product Description popup.authors Anikeeva Katerina S. Kochin Valeriy М. Lunyova Victorija A.
