Abstract

We have measured the penetration depth and conductivity of high Tc superconductor at liquid nitrogen temperature by using microwave transmission method. After that we obtain the frequency dependance of surface resistance in high Tc superconductor. Experimental results show that the surface resistance of high Tc superconductor is proportional to the square of frequency as theoretical prediction. The advantage of microwave transmission method is broadband and easy to use.
