Physical principles for designing a multipurpose set of high 𝑄 -factor quasioptical and corrugated resonators with automatic frequency tuning ( 𝑄 > 6 × 1 0 4 , V S W R < 1 . 6 ) that can operate in the frequency band from 37.5 to 400 GHz are presented. The electrodynamical calculation methods of resonators, the constructive particularities of resonators, the methods and results of the experimental researches are considered. This set of resonators can be used as a universal measuring resonator for measuring radio-signal fluctuations and parameters of different media, in particular, nanotube composites and high-temperature superconductors.
