| Abstract: | The microwave surface resistance of YBCO superconducting material was measured in a TE_(103) rectangular cavity at the 3cm waveband. We observed that the quality factor Q of the cavity changed abruptly at the transition temperature of the superconductor. The surface resistance at liquid Nitrogen temperatures was found to be about 20% of its normal resistance:The variation in surface resistance with sample thickness was also observed in the experiment. |
