Abstract After the discovery of new metal oxide superconductors with higher transition temperatures raised the possibility of a new class of superconducting microwave devices operating at temperatures well above liquid He, a feasibility study of the superconductor devices at r.f., microwave, and millimeter-wave frequencies, i.e., cavity resonator, transmission lines, waveguide, mirror, and antenna, was started at JAERI (Japan Atomic Energy Research Institute), Tokai in April 1987. In order to examine the feasibility of such devices and to investigate the nature of the superconductivity in these new superconductors, we have studied the microwave response of the oxide superconductors. In addition, we have also studied the fabrication and microwave properties of these devices using the new superconductors. We report here the status of the feasibility study, especially about the BSCCO and YBCO superconductor cavities, and the r.f. characterization apparatus using several cavity resonators. The cavities have potential applications for particle accelerators, resonant filters, ultrastable clocks, and so on.
