PHASE-LOCKED 2-D JOSEPHSON JUNCTION ARRAYS AS SUBMILLIMETER OSCILLATORS

摘要

This letter presents the results of numerical simulations for phase-locked 2-D Joseph- son junction array oscillator. The simulation result shows that the junctions of 2-D array can mutually phase-locked in a considerable area if the parameters can be carefully selected. The oscillators are formed with up to 33 identical Nb/AlOx/Nb junctions, and the junctions are con- nected with Nb microstrip resonators. Optimum structure parameters for oscillator circuit design can be obtained with these simulation results.
