Microwave Measurements on Patterned High Temperature Superconducting Thin Film Circuits

Abstract
The microwave surface resistance and dispersion of laser deposited YBaCuO films patterned in the form of a meander line have been measured from L through Ku-band at temperatures from 5 to 90K. Surface resistance values below 1 mΩ were demonstrated at 10 GHz and 79K. The results show great promise for the realization of effective high-Tc superconductive passive microwave components in the near future.
