摘要

将弓形载荷弯曲天线应用于高tc超导约瑟夫逊结太赫兹探测器，以提高耦合效率。通过测量每入射功率下一阶夏皮罗阶跃的最大值来评价天线的性能。实验结果表明，该方法能较好地拟合耦合效率。因此，太赫兹天线可以在传统的矢量网络分析仪之外，以一种新的方式进行表征。

Terahertz Antenna Characterization by the Josephson Effect for Superconducting Terahertz Detectors

Bowtie loaded meander antenna was applied on a high-Tc superconducting Josephson-junction terahertz detector to enhance the coupling efficiency. The antenna performance is evaluated by a new method based on measuring the maximum of the 1st-order Shapiro step under per incident power. The experiment indicates that the outcome by this new method fits the coupling efficiency well. Thus, THz antenna can be characterized in a new way besides the traditional vector network analyzer.
