BASIC CELLS FOR PHASE-LOCKED 1-D AND 2-D JOSEPHSON-JUNCTION ARRAYS

The results of a numerical simulation of a few Josephson-junction unit cells and phase-locked 1- and 2-D arrays based on the cells are prese nted, The numerical simulation was performed by means of PSCAN program in the frame of both RSJ and Werthamer models of Josephson junctions with finite intrinsic capacitance, It is shown that 1-D arrays, as wel l as 2-D arrays, can keep a phase-locked oscillation state within wide critical current margins \Delta I-c\ up to 40%, The possible fabricat ion and use of the phase-locked structures are discussed.
