Loop inductance of a Josephson junction interferometer

Abstract

In a Josephson junction interferometer, the current flow between the junctions is not uniform along the stripe line. The current is crowded around the junctions and becomes uniform along the strip line only when it is far away from the junction area. The inductance of such a structure with nonuniform current flow is analyzed. Several analytical formulas are derived to calculate the loop inductance of a Josephson junction interferometer.
