The characteristic feature of the considered structures is complex composition of the elements which have different character of field scattering and functionality. Investigation is referred to the development of new physical principia of the design of UHF system for the field control and to the improvement already known one. The resonance and band frequency, polarization selector, the phase corrector, the dielectrometer, the absorber are considered in this project. This material is progress of the Research project which was held at the theoretical radiophysic department of the Kharkov National University in 2002-2005 years. Objects of the investigation are rectangular waveguide of finite length with identical diaphragms, finite periodic sequence of the frequent grids from perfectly-conducting and infinite thin stripin free space, the passing cylindrical resonator with corrugated sidewalls. Investigation method combines direct and approximate methods. The method of the moments, method of the matrix functions and circuits theory, the method of equivalent boundary conditions were used as the part of the investigation method. The scattering fields for the monochromatic plane wave and Gauss beam for two- and one-mode regimes were shown in the report. The investigations of the eigen and forced oscillations of the resonator with impedance sidewalls and eigen waves of the rectangular corrugated waveguide were worked out. The conditions of the high-Q oscillations forming and phenomenon of the polarization transformation were clarified in the report. There was presented the theory of the dielctrometer for the liquid.
