Effects of Bias Current Non-Uniformity on the SQUID Array (SQA) Response

The amount of current being received by each junction affects the performance of a parallel coupled Superconducting Quantum Interference Device (SQUID) Array (SQA). Previous modeling utilized a uniform bias current input for each Josephson junction (JJ) in a parallel SQA. In this work we explore the effects of the bias current spreading out non-uniformly in the superconductor as a function of the number of JJ's in parallel. We use a lumped model approach combined with pre-calculated cross-sectional current distribution as a function of controllable film properties.
