Transition from Turing stripe patterns to hexagonal patterns induced by polarized electric fields

摘要

The effect of a circularly polarized electric field on the Turing stripe patterns is studied.The numerical results show that stripe patterns may change to hexagonal wave patterns by choosing the intensity and the frequency of the circularly polarized electric field suitably.Our findings indicate that a pattern tends to organize itself to the pattern with the same symmetry of the applied field with the fact that compared to the stripe patterns,hexagonal wave patterns possess hexagonal symmetry which is closer to the rotation symmetry of the circularly polarized electric field.
