Frustrated Synchronization in Two Coupled Polygonal Oscillatory Networks

In this study, synchronization phenomena observed in coupled polygonal oscillatory networks with frustration is investigated. We focus on the amplitude of each oscillator when the coupling strength is changed. By using computer simulations and circuit experiments, we confirm that the amplitude of the shared and the other oscillators obtains different value by increasing the value of the coupling strength. Furthermore, theoretical analysis is applied to solve the amplitude and the phase differences between the adjacent oscillators.
