Dielectric resonators with azimuthal waves for investigations of high-T/sub c/ superconductors

Investigation of microwave properties of high-temperature superconductors can be carried out In a resonator or distributed structures. The difficulties arising in creation of the samples of metaloxide superconductors in the form which is different from the plane or cylindrical one, as well as the difficulties connected with the applying a superconducting coating to different surfaces and the necessity of studying the films of new materials stimulate a search of the new methods of investigation.
