摘要：

In this paper,the evolution of the pattern transition induced by the vortical electric field (VEF) is investigated. Firstly,a scheme is suggested to generate the VEF by changing the spatial magnetic field. Secondly,the VEF is imposed on the whole medium,and the evolutions of the spiral wave and the spatiotemporal chaos are investigated by using the numerical simulation. The result confirms that the drift and the breakup of the spiral wave and the new net-like pattern are observed when different polarized fields are imposed on the whole medium respectively. Finally,the pattern transition induced by the polarized field is discussed theoretically.
