基于电感耦合约瑟夫森结的新型毫米波方向探测器设计
Inductively coupled Josephson junctions for high-precision detection of the millimeter wave direction
利用一对通过电感耦合的约瑟夫森结,设计了一种新型的毫米波探测器。探测器模拟了寄生蝇的听觉结构,可以放大两个约瑟夫森结接收到的毫米波之间的微弱相位延迟,进而精确分辨毫米波的方向。采用数值计算方法进行模拟,结果表明通过电感耦合的两个约瑟夫森结确实可以将微弱的相位延迟放大到可以观测的程度。当两个约瑟夫森结之间的距离为270μm,被测波波长为3mm时,定向误差可以被控制在0.1 以下。
Based on a pair of inductively coupled Josephson junctions, the authors design a new type of millimeter wave sensor which imitates the aural structure of parasitoid flies. Depending on the phase delay between the two Josephson junctions, the sensor can accurately distinguish the direction of millimeter wave source. Further more, the sensor is simulated by using numerical methods. Simulated results show obvious difference of the inductively coupled Josephson junctions when the time delay is 0.01ps. In addition, when the distance between the two Josephson junctions is 270μm, and the wave length is 3mm, the direction detection error can be less than 0.1 degree.
