Abstract

The “self-synchronization” effect is studied, i.e., the exact coincidence of Josephson generation frequencies in intersecting superconducting bridges. A parametric interaction appears, which is due to the proximity effect, i.e., to the change in the order-parameter modulus in the region of the junction contact. The “voltage locking” region in the plane of the current-transport and current-control circuits is determined by computer-aided numerical calculations.
