Abstract
Resonance regions similar to the Arnol'd tongues found in single oscillator frequency locking are observed in experiments using a spatially extended p eriodically forced Belousov-Zhabutinsky system. We identify six distinct 2: 1 subharmonic resonant patterns and describe them in terms of the position- dependent phase and magnitude of the oscillations. Some experimentally obse rved features are also found in numerical studies of a forced Brusselator r eaction-diffusion model.
