Pattern formation in self-oscillating systems was examined as a function of an external periodic perturbation. Two reaction-diffusion models - the FitzHugh-Nagumo and Brusselator - and an amplitude equation were also examined numerically to test the analytical predictions. The subharmonic resonant case - where the system locks at one-forth driving frequency - was analyzed, and the formation of four-phase spiral patterns was observed at low forcing amplitudes.
