Scroll waves meandering in a model of an excitable medium

We study numerically the dynamics of a scroll wave in a three-dimensional (3D) excitable medium in the presence of substantial meandering of the corresponding 2D spiral wave in the Aliev-Panfilov model. We identify three types of dynamics of the scroll wave filament-quasi-2D, periodic, and aperiodic meandering-and we study their dependence on parameter settings and thickness of the medium
