Abstract

Two types arrays of annular half-wave and electrically small antennas with typical sizes of the elements corresponding to 1/10 of the wavelength at SubTHz band with integrated superconductor–insulator–normal metal–insulator–superconductor (SINIS) bolometers have been developed, fabricated and experimentally studied. We performed numerical modeling of the full structure and use additional reference channels in experimental studies to enhance the accuracy of the spectral response estimations of receiving arrays. In experiments three reference channels were used for normalization of the spectral response: a pyroelectric detector outside the cryostat, and two cold channels—a RuO₂ bolometer and on-chip thermometer comprising series array of NIS-junctions.

SINIS测速计对半波和电小天线阵列的频谱响应

摘要

已开发，制造出两种类型的环形半波天线和小型电子天线，其典型尺寸的元件对应于SubTHz波段波长的1/10，并集成了超导体-绝缘体-普通金属-绝缘体-超导体（SINIS）辐射热计并进行了实验研究。我们对整个结构进行了数值建模，并在实验研究中使用了其他参考通道，以增强接收阵列的频谱响应估计的准确性。在实验中，使用三个参考通道对光谱响应进行归一化：低温恒温器外部的热释电检测器，以及两个冷通道-RuO ₂热辐射计和包含一系列NIS结阵列的片上温度计。
