Abstract
The surface resistance of high-quality YBa/sub 2/Cu/sub 3/O/sub 7/ superconducting films measured over a frequency range from 10 to 500 GHz using high-speed optoelectronic techniques is discussed. A direct comparison is made with the surface resistance of gold and superconducting niobium conductors. Using the measured surface resistance, the propagation characteristic of interconnects based on YBa/sub 2/Cu/sub 3/O/sub 7/ superconductors at 77 K is simulated and compared to that of gold transmission lines at 77 K and superconducting niobium lines at 7.7 K.Keywords
