Рішення задач дифракції поверхневих хвиль на площині з довільно заданим розподіленням імпедансу Head Pogars'kyj S.O.,Zvyagintsev A.O., Registration Date 27-03-2002 Organization Kharkov National University named after V.N.Karazin popup.description2 The subject of investigations: the methods of analysis, functional elements, wideband waveguide systems of UHF and SHF bands, PC technologies.The goal of investigations: the main goal of investigations is creation of PC technologies of wideband waveguide UHF and SHF systems analysis. By the uniform asymptotic theory method solution of electromagnetic waves diffraction problem by impedance half plane has been suggested The carried out analysis showed that the modification of physical-geometrical parameters of scatterers and sources of radiation allow to control parameters of scattered fields effectively and, in partially, to control parameters of directional diagram. By the spectral operators method the diffraction of T-eigenwave of coaxial line the diffraction problem by semi-infinite tangentional slots has been suggested. The key-problem is the problem of diffraction by single slot in coaxial line. The possibility of transition to the system with finite number of slots has been shown.
