三层弱循环耦合可激发介质中螺旋波动力学
The dynamics of spiral waves in three-layer excitable medium with circular feedback coupling
摘要
Abstract
The dynamics of spiral wave in a three-layer excitable medium with circular feedback coupling is studied,based on the Bar model. The numerical results show that the drifting or meandering of spiral waves in the subsystems can be observed when the coupling strength is small.When the coupling strength is slightly big,the interaction between subsystems may cause spiral waves in some subsystems to move out of the boundaries of the subsystems.The subsystems return to rest state.In addition,the interaction may generate the transition from spiral wave state to target wave or turbulence states in some subsystems.The phenomenon that the asymptotic state of a subsystem depends on the initiation condition is observed.With the further increase of the coupling strength,the approximate generalized synchronization of the spiral waves in three subsystems is established.When the coupling strength is bigger,the spiral waves evolve into turbulence.关键词
