abstract

  • Electrical time domain measurements and transmission response measurements were made using a 31-cm-long, YBaCuO superconducting thin-film microstrip line and a YBaCuO ground plane, each on separate 1-cm LaGaO3 substrates, with a 125-μm sapphire substrate serving as the dielectric insulator. Degradation of the performance of the line for currents up to the critical-current density and for magnetic fields moderately above the lower critical magnetic field HC1 were evaluated in a variety of simple measurements. In addition, an evaluation of an optically switched segment of a superconducting microstrip line on a zirconia substrate is described. Direct evaluations of pulse distortion are not possible for these long serpentine lines on small substrates due to electromagnetic coupling between adjacent line segments. However, this coupling gives rise to distinctive transmission responses which may aid the evaluation of line performance.
