Abstract

Synchronization of a spiral by a circularly polarized electric field (CPEF) in reaction-diffusion systems is investigated since they both possess rotation symmetry. It is found that spirals in different regimes (including rigidly rotating, meandering, and drifting spirals) can be forced to be rigidly rotating ones by CPEFs. Moreover, the rotational frequency of the entrained spiral is found to be synchronized with the frequency of the electric field in a ratio of 1:1.

摘要

由于反应扩散系统和圆偏振电场（CPEF）都具有旋转对称性，因此研究了反应扩散系统中圆偏振电场对螺旋波的同步作用。研究发现，不同状态下的螺旋波（包括刚性旋转螺旋波、蜿蜒螺旋波和漂移螺旋波）都可以被圆偏振电场强迫成为刚性旋转螺旋波。此外，还发现被捕获螺旋波的旋转频率与电场频率以1:1的比例同步。
