摘要：
Chaos synchronization between Josephson junctions coupled bidirectionally with coupling time-delay is investigated. The results are compared with the case of junctions coupled in a unidirectional and mixed (both unidirectional and bidirectional couplings) configurations. We establish that bidirectional coupling between the junctions deteriorates synchronization quality significantly, and as such should be avoided in cases when a large number of the Josephson junctions are to be synchronized. Synchronized Josephson junctions can be a source of Terahertz radiation with enough power, which is promising for practical applications in numerous scientific areas. (C) 2017 Elsevier GmbH.
