Abstract
Numerical simulations and analytical arguments for the resonant behavi or of periodically perturbed rotating spiral waves in systems with bro ken rotational symmetry are presented. Resonance, i.e., the displaceme nt of the rotation center along a straight line, appears always if the perturbed rotation does not match the symmetry given by the active me dium supporting the wave. For the Z(2) case, simulations in a simple t wo-component reaction-diffusion model have been carried out. For the c ase of arbitrary rotational symmetries Z(d), a general resonance condi tion is derived.
