Mutual inductance effect of two Chua's circuit induce phase synchronization

Typically, the circuit realization of synchronization is to impose an external signal which is periodic on the response system. Herein we propose a novel study which is different from the previous methods using feedback to achieve synchronization. Our work is to make the individual inductance of two Chua's circuit systems produce mutual inductance effect, and achieve bidirectional coupling of two Chua's circuit systems. The synchronization phenomenon is observed successfully, and we demonstrate the analysis of phase synchronization further.
