谐振型Josephson隧道结与外加微波的磁耦合(Ⅰ)

谐振型Josephson隧道结在建立Josephson电压基准的工作中受到广泛的应用。本文从受迫振动的模型出发,运用磁耦合的边条件,对波导中的结作了处理,得到了和实验相符的结果。在实验中我们对波导系统的短路装置作了适当改进,减少了微波漏损并改善了短路条件。低温实验的结果表明这种改进是有效的。 关键词：

MAGNETIC COUPLING BETWEEN THE RESONANT JOSEPHSON TUNNEL JUNCTION AND THE APLLIED MICROWAVE (Ⅰ)

The resonant Josephson tunnel junction is used generally in the Josephson voltage-standard works. This paper starting from the forced vibration model, taking account of the magnetic coupling boundary condition, treats a junction in the waveguide system, and result which agrees with those of the experiments is obtained. In the experiment we improved the short circuit unit of the waveguide, system, thus the microwave leakage was reduced and the short circuit condition has been improved. The result of our experiment at low temperature shows that the improving is effective.
