Design and Evaluation of Three-Dimensional Integration of Superconducting Multilayer Waveguides for Localized Electromagnetic Waves

多层超导集成电路中带状线电感的设计与评价是研究的重点。对夹在两个地平面之间的超导带状线的解析表达式给出了精确的结果。计算了两条超导带状线之间的互感。结果表明，两地平面接触的位置起着重要的作用。对超导接地平面中的电流分布进行了数值模拟。还演示了与约瑟夫森器件相关的其他结果，包括SFQ-DAC的两个电路元件。

Design and evaluation of stripline inductances in multi-layered superconducting integrated circuits are the research targets. The analytical expression for a superconducting stripline sandwiched by two ground planes provided accurate results. Mutual inductances between two superconducting striplines were evaluated. The results demonstrated that the positions of contacts between two ground planes played important roles. Current distribution in a superconducting ground plane was numerically presented. Other results related to Josephson devices including two circuit elements for an SFQ-DAC were also demonstrated.
