The resonance interaction between two modes is investigated using a two-layer coupled Brusselator model. When two different wavelength modes satisfy resonance conditions, new modes will appear, and a variety of superlattice pattes can be obtained in a short wavelength mode subsystem. We find that even though the wavenumbers of two Turing modes are fixed, the parameter changes have infl uences on wave intensity and patte selection. When a hexagon patte occurs in the short wavelength mode layer and a stripe patte appears in the long wavelength mode layer, the Hopf instability may happen in a nonlinearly coupled model, and twinkling-eye hexagon and travelling hexagon pattes will be obtained. The symmetries of pattes resulting from the coupled modes may be different from those of their parents, such as the cluster hexagon patte and square patte. With the increase of perturbation and coupling intensity, the nonlinear system will con-vert between a static patte and a dynamic patte when the Turing instability and Hopf instability happen in the nonlinear system. Besides the wavenumber ratio and intensity ratio of the two different wavelength Turing modes, perturbation and coupling intensity play an important role in the patte formation and selection. According to the simulation results, we find that two modes with different symmetries can also be in the spatial resonance under certain conditions, and complex pattes appear in the two-layer coupled reaction diffusion systems.
