Abstract: | 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. |
