Planar Transmission Line Resonators from YBa2Cu3 O7-X Thin Films and Epitaxial SIS Multilayers 
The authors have grown c-axis-oriented YBa2Cu 3O7-x (YBCO) thin films and epitaxial YBCO/NdAlO 3/YBCO trilayers by sputtering. From the YBCO films, coplanar half-wavelength transmission line resonators were patterned. At 77 K the unloaded quality factors of coplanar stripline resonators were up to 2570 at 5.6 GHz. The attenuation constant of such a line was evaluated to be 0.6 dB/m at 77 K and at 5.6 GHz. Coplanar waveguide resonators yielded quality factors up to 1200 at 77 K and at 6.2 GHz res...    »
