Dynamic Behavior of Phase Synchronization of Chaos

The dynamic nature of phase synchronization between chaotic outputs and injected periodic signals is investigated. We find that the collapse of stroboscopic section from global distribution to local one and the loss of homogeneity of stroboscopic sections in chaotic attractors for different phases are the key features of this kind of phase synchronization, meanwhile the overall structure of chaotic attractor is not affected apparently by the phase synchronization.
