Objects of the study: piezoelectric controlled dielectric structure in the microwave range, the frequency dependence of permittivity, dielectric loss of piezoelectric single crystals with a small microwave absorption. The purpose of work: Design and study beyond the high-frequency oscillatory solid systems with electro-mechanical and optical management amplitude, frequency and phase of microwave signals based on a detailed study of active dielectrics with low microwave absorption. Recommended area of use: How to create the special microwave dielectric materials, as well as microwave devices with an electrically controlled based on the characteristics of dielectric resonance. Key words: ultra-high frequencies, dielectric materials, microwave ceramics, dielectric resonant elements regulating the resonant frequency filters with adjustable features,phase shifters. Key results are: 1 designed, manufactured and studied the characteristics of filters and phase NVCH in the meter and cm bands on the basis of regular and resonance of planar and volumetric dielectric structures. 2 studied the microwave characteristics of piezoelectric single crystals, siliko-, German-titanium silenitov, langasitov, Galatians and alyuminatov RZE. 3 Designed Actuators made a number of different geometry and small dimensions, with a voltage control? 30 volts, suitable for microwave devices. 4 developed and produced a measuring device for the study prepared for the DR microwave. Dielectric resonators are investigated with the main type of oscillation. Show their suitability for the construction of electrically controlled microwave phase, switches, filters. 5 Obtained results shows the perspective of implementaion of thin dielectric resonators for use in microwave technology Conditions for obtaining the report: under the contract, 252171 str.
