  • Process and device for microwave surface resistance determination
    Patent number: 5506497
    Abstract: A process for determining a surface resistance to microwave energy of a superconductive film provides a metallic cavity resonator whose resonator cavity is defined by metallic walls, and positioning a superconductive film whose microwave surface resistance is to be measured as at least part of a wall of the cavity. A dielectric body is applied to a surface of the film and microwave energy is coupled to the cavity through an input antenna and microwave energy is coupled out of the cavity by an output antenna at which signals are produced as a measure of the microwave surface resistance of the film.
