A phase diagram for two weakly coupled Belousov-Zhabotinsky systems was experimentally obtained as a function of coupling strength and the difference between the natural frequency of the constituent cells. The results indicate existence of six phases. To find out a universal features for the weak coupling, kinetic equations for phase and radius of limit cycle were derived from ordinary reaction diffusion equations in a two component system. Simple models of the coupling states from the simple equations of phase and radius explained qualitative features of the experimental results.
