Item Electrodynamic properties of defects in photonic crystals(Sumy State University, 2017) Petrovskyi, Mykhailo Vasylovych; Петровський, Михайло Васильович; Петровский, Михаил ВасильевичNow the electrodynamic systems of terahertz range devices are being improved due to the rapid development of synthetic material media possessing the property of periodicity in several directions which are call photonic crystals. The implementation of field interaction of photonic crystals with electron beams or dielectric waveguides is based on the formation of linear disturbances of their periodicity, these disturbances having strongly expressed waveguide properties.Item Perspectives of application of new modifications of resonant quasi-optical structures in EHF equipment and electronics(Telecommunications and Radio Engineering, 2007) Vorobiov, Hennadii Saveliiovych; Воробйов, Геннадій Савелійович; Воробьев, Геннадий Савельевич; Petrovskyi, Mykhailo Vasylovych; Петровский, Михаил Васильевич; Петровський, Михайло Васильович; Журба, Вячеслав Олегович; Журба, В`ячеслав Олегович; Zhurba, Viacheslav Olehovych; Ruban, А.I.; Belous, О.I.; Fisun, А.I.General properties of the "classic" open resonators without heterogeneities as the base devices while determining the particularities of new modifications of the millimeter-wave and sub-millimeter-wave band resonant structures are disclosed in the paper. The properties of open resonators with periodic metal heterogeneities, coupled open resonators as well as various modifications of resonant metal-dielectric structures are considered. The way for further investigation of new modifications of the resonant quasi-optical structures is determined from the point of view of optimization of their output parameters.
