A set of measuring microwave resonators

An universal set of broadband high-Q measuring resonators operating in a frequency band of 0.6–180 GHz is described. The resonators may be used for physical investigations, measuring parameters of different media, and in spectroscopy, holography, radio-astronomy, communication engineering, and physical electronics. The microwave resonators with a mechanical frequency tuning range of 1/2 octave and higher and a loaded Q-factor of no less than 105 are created, and there is a possibility of electronic frequency adjustments in them.
