Synchronization Phenomena of Coupled Chaotic Circuits Network with Coupling Strength Depending on Number of Degree

摘要

We investigate the influence of direct coupling and indirect coupling for synchronization state in the network. The node of the network is expressed by chaotic circuit. This complex network is designed that a node has two or more links except for one node with scale free property. The coupling strength is determined depending on the number of links between the nodes. In this investigation, we find that not only the direct coupling but also the indirect coupling by the path is strongly related for synchronization state.
