Experimental observation of multirhythmic pattern in chains of Rossler circuits

The influences of parameter mismatches on multirhythmic pattern in chains of coupled Rossler circuits are explored experimentally. The parameter mismatches in coupled chaotic oscillators are found helpful to form a kind of multirhythmic pattern as reported in chains of biological coupled oscillators Phys. Rev. Lett. 92 228102. Moreover, a new type of multirhythmic pattern based on the envelope of time series is observed.
