ABSTRAKT

This work is the continuation of series of works on research of physics of resonant phenomena in waveguide junctions of various cross-section [1, 2, 4, 6, 8, 11, 12] and to their using for measurement of material electric characteristics [5, 7, 9, 10, 13]. The electrodynamic and numerical analysis of eigen Q-factor of electromagnetic modes of H-type (as the most high-quality) in waveguide junction of cylindrical - rectangular waveguides, filled by dielectric have been carried out in this work. The comparative characteristic of eigen Q-factor waveguide junctions of various cross-section was given: cylindrical - radial waveguides, rectangular - rectangular waveguides, cylindrical -rectangular waveguides. The recommendations on using of concrete type of waveguide junctions for measurement of dielectric losses of the certain materials were given.
