Abstract
Recently there is growing interest in Superconducting Quantum Interference Filters (SQIFs) in the science community. Much in the way that antenna array technology has moved from uniform arrays to non-uniform, sparsely populated arrays, SQIF devices open the trade space from traditional uniform SQUID arrays to unconventional SQIF structures making these mesoscopic quantum devices (for RF reception) a feasible concept. Computational modeling of SQIFs exhibits a non-periodic voltage response vs. external flux where an anti-peak is present only around the zero applied magnetic field. Improved dynamics range is investigated in this work by considering inductive coupling, number of loops in an array, and unconventional grating structures. We show that changes in these parameters can lead to a significant performance enhancement.
