摘要
为了精确测量高温超导体的表面电阻，给出了一种系统的截锥腔设计理论。这种腔避免了模态退化，这是一个问题，如果使用圆柱腔。此外，它提供了相当高的灵敏度，关于表面电阻的测量。介绍了一种52 GHz的测量系统，并给出了三个样品的测量结果。在52 GHz下，三种薄膜的残余电阻在5 ~ 10 m ω范围内。测量精度达到+或0.5 m ω。
MM-wave surface resistance measurements of HTS films using a highly sensitive cavity
For the precise measurement of surface resistance of HTSs (high-temperature superconductors), a systematic design theory for truncated cone cavities is given. This kind of cavity avoids mode degeneration, which is a problem if cylindrical cavities are used. Also, if offers a considerably higher sensitivity with regard to surface resistance measurements. A measurement system at 52 GHz is described and results for three samples are given. The residual resistances of the three films were in the range of 5 m Omega to 10 m Omega at 52 GHz. A measurement accuracy of +or-0.5 m Omega has been achieved.<>
