Abstract

We studied the stability of vortex waves in 2D homogeneous excitable media using a cellular automaton model on a randomized square lattice. We performed two different sets of simulations using both square and circular regions for the interaction neighborhood. In both cases, the spontaneous breaking of the vortex waves was eliminated by randomizing the positions of the lattice nodes beyond a minimum length scale λc. This scale was substantially smaller for the circular interaction region.
