Abstract

In this paper, we developed and investigated superconducting integrated circuits designed to match the impedances of a generator represented by a flux-flow oscillator based on a long Josephson junction and a detector based on a superconductor–insulator–superconductor tunnel junction in the subterahertz frequency range. The structures were modeled using the transfer matrix method. Designs were also calculated in the program of numerical three-dimensional modeling. A qualitative agreement was found between the results obtained by two methods. Three samples with different topologies were designed, covering the frequency range of 250–680 GHz at a level of –2 dB.

超导集成匹配电路设计

摘要

在本文中，我们开发并研究了超导集成电路，旨在匹配发电机的阻抗，发电机的阻抗为基于长约瑟夫森结的磁通流振荡器和基于超导体-绝缘体-超导体隧道结的探测器，在太赫兹频率范围内。使用传递矩阵方法对结构进行建模。设计也在数值三维建模程序中进行了计算。两种方法获得的结果之间存在定性一致性。设计了三个具有不同拓扑的样本，覆盖 250-680 GHz 的频率范围，电平为 –2 dB。
