Abstract

We have measured the surface impedance of two different orientations of thin films of YBa₂Cu₃0_7-8 (YBCO) at 100 and 150 GHz. The surface resistance drops rapidly below the transition temperature, but the loss at low temperatures is in disagreement with the convential BCS theory. The measured temperature, frequency, and orientation dependence are presented and discussed.
