Abstract
We present experimental and theoretical results showing that the distribute d electromagnetic environment of a Josephson junction array can cause the j unctions in the array to synchronize. Based on our experimental results and our distributed array model, we find that an external load is not necessar y for junction synchronization. Also, we show that the high-frequency perfo rmance of an array can be significantly better than the performance of a si ngle isolated junction. [S0163-1829(99)01034-6].
