Effect of Coupling Strength on Synchronization Phenomena in Chaotic Circuits with Unidirectional Coupling

In this study, a chaotic circuit called the Nishio-Inaba circuit was coupled with unidirectional coupling. Therefore, we investigated changes in the synchronization phenomenon due to differences in coupling strength between circuits. When three Nishio-Inaba circuits are connected, if the coupling strengths are equal, the synchronization rate will be higher for pairs with equal parameters. On the other hand, we found that varying the coupling strength changes the synchronization phenomenon between circuits.
