在He等人所做的嵌入到Fabry-Perot谐振腔中约瑟夫森结阵列的微波辐照研究基础上,提出了同时实现约瑟夫森结阵列阻抗匹配和相位锁定的方法,进行了相关的电磁仿真和数值计算.双晶约瑟夫森结阵列被制作在YSZ双晶基片上,同时被嵌入到Fabry-Perot谐振腔内.通过在基片上制作与结阵列集成的串联馈电半波偶极天线阵,并对其结构进行优化实现了结与天线的匹配,数值计算表明结的辐射效率达到94%;利用天线阵辐射场的特征和对模型合理的设计,使Fabry-Perot谐振腔和基片同时谐振在合适的模式下,从而使结阵列与谐振器之间产生强烈的高频电磁耦合,相关的数值计算表明这种方法能有效实现结阵列的电压自锁定和相位互锁定.文中的设计思想和计算结果对约瑟夫森结阵列用于微波信号源和电压标准等具有参考价值和指导意义.

英文摘要：

We proposed a method for implementing impedance matching and phase locking of Josephson junction arrays based on He＇s previous report on the coupling mechanism of a millimeter wave radiation to bicrystal Josephson junction arrays embedded in a Fabry-Perot resonator,and relevant electromagnetic simulations and numerical calculations were performed. A bicrystal Josephson junction array was fabricated on a YSZ bicrystal substrate,and embedded in a Fabry-Perot resonator. Impedance matching was implemented by integrating an optimized half-wavelength dipole array fed in series with the junction array,and numerical calculations showed that the radiation efficiency of a single junction reached 94%. Through making good use of the radiation characteristics of the antenna array and optimizing the model,the FP resonator and the substrate can be driven to resonate in proper modes respectively,which benefits the high frequency electromagnetic coupling between the junction array and the resonators. The numerical simulations proved that this method is effective for realizing self-voltage locking and mutual-phase locking of junction arrays. The method proposed in this paper and calculation results are valuable for guiding the applications of Josephson junction arrays in THz signal generators and voltage standards.
