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.
On the basis of the microwave radiation research of Josephson array embedded in the Fabry-Perot resonator by He et al., The method of realizing the impedance matching and the phase locking of the Josephson junction array is proposed. The related electromagnetic simulation and Biphasic Josephson junction arrays are fabricated on a YSZ bimorph substrate embedded in a Fabry-Perot resonator by fabricating a series-feed half-wave dipole antenna array integrated with a junction array on a substrate and The structure of the Fabry-Perot resonator is matched with the antenna. The numerical calculation shows that the radiation efficiency of the junction reaches 94%. Using the characteristics of the radiation field of the antenna array and the reasonable design of the model, Mode, so that a strong high-frequency electromagnetic coupling between the array and the resonator is generated, and the numerical results show that this method can effectively realize the voltage self-locking and phase-locking of the array. The design idea and calculation results Josephson junction array for microwave signal sources and voltage standards have a reference value and guidance.
