A theory for spiral wave drift induced by ac and polarized electric fields in chemical excitable media

Abstract Spiral waves are shown to undergo directional drifts in the presence of ac and polarized electric fields when their frequencies are twice of the spiral frequencies. Here, we propose a quantitative description for the spiral wave drift induced by weak electric fields, and provide the explici...
