Abstract
We report on numerical simulations of 10- and 19-layer stacked Josephson ju nctions. Simulations are performed using the experimentally feasible parame ters for Nb/Al-AlOx/Nb junctions. With an appropriate choice of parameters such as magnetic field and coupling, the current-voltage curves of N-layer stacks systematically indicate in-phase locking among the inner N-2 junctio ns. The simulation results suggest that multilayer Josephson junctions are very promising as submillimeter-band high-power oscillators. (C) 1998 Ameri can Institute of Physics. [S0003-6951(98)02430-9].
