| Abstract: | Oscillations in the coupled systems can be suppressed by varying density of mean field. The presence of parameter mismatch or time delay interaction in such systems enhances the amplitude death (AD) region in parameter space. This behavior of stability of steady state is analyzed by analytical as well as numerical studies of specific cases of limit-cycle and Rössler oscillators. Experimental evidence of AD is also shown, using an electronic version of the Chua’s oscillator. |
