Description

 An electromagnetic wave diffraction process on inhomogeneities in waveguides is investigated. The development of effective methods for analysis of electromagnetic wave diffraction process in waveguides is performed. There are also developed novel numerical models of electromagnetic wave diffraction process in waveguide transmission lines. The integral equation method, mathematical methods of microwave electrodynamics, tensor Green’s functions, methods of applied mathematics and numerical analysis are also improved for such class of problems. The Schwartz alternating method has been developed in order to apply it to a wider class of exterior and interior electromagnetic wave diffraction problems; the three-dimensional electromagnetic wave diffraction problem on a junction of two rectangular waveguides has been solved for the first time using Schwartz method; diffraction problems on an infinite parallel plate PAA with aperture inhomogeneities have been solved using Schwartz alternating method with optimal iteration algorithm; the vector three-dimensional diffraction problem on a cascaded junction of three waveguides have been solved for the first time using overlapping partial domain method. Application - development, design and production of microwave devices, passive and active waveguide devices, antennas and antenna systems of centimetre and millimetre wave bands, including phased array antennas.
