论文摘要
我们基于超导量子干扰设备（Squid）实现微波的广泛调谐相变，并在实验和理论上研究。在不同的频率下，单位传输系数，$ | s_ {21} | = 1 $，可以从理论上沿曲线实现，其中相移可通过磁通量控制。制造的设备由三个等距的鱿鱼组成，打断了传输线。我们用两个参数（电容和电感）模拟了沿传输线不同位置嵌入不同位置的每个鱿鱼，我们从实验中提取的值。在我们的实验中，相位移位的可调性从$ 0.07 \timesπ$到$ 0.14 \timesπ$径向沿全传输曲线，输入频率范围从6.00到6.28〜GHz。报告的测量与模拟非常吻合，这对于不同应用的相位变速器的未来设计工作非常有希望。
We implement a broadly tunable phase shifter for microwaves based on superconducting quantum interference devices (SQUIDs) and study it both experimentally and theoretically. At different frequencies, a unit transmission coefficient, $|S_{21}|=1$, can be theoretically achieved along a curve where the phase shift is controllable by magnetic flux. The fabricated device consists of three equidistant SQUIDs interrupting a transmission line. We model each SQUID embedded at different positions along the transmission line with two parameters, capacitance and inductance, the values of which we extract from the experiments. In our experiments, the tunability of the phase shift varies from from $0.07\timesπ$ to $0.14\timesπ$ radians along the full-transmission curve with the input frequency ranging from 6.00 to 6.28~GHz. The reported measurements are in good agreement with simulations, which is promising for future design work of phase shifters for different applications.
