The dynamics of spiral waves under external modulation of excitability is studied experimentally in a light-sensitive convection-free Belousov-Zhabotinsky medium. When varying the intensity of applied illumination periodically, the experiments reveal strong dependence of the resulting trajectories o

We study frequency locking and resonance of spiral waves in an active medium subjected to periodic forcing with adjustable frequency. The experiments are carried out with a modified Belousov-Zhabotinsky system whose excitability is light-sensitive. In the meander regime of compound rotation we find
