Onset of resonance in chaotically driven systems

We investigate the onset of chaotic resonance (CR) behavior by studying the dynamics of chaotically driven bistable systems near the crisis bifurcatio n point. Our analysis reveals the existence and identification of a charact eristic natural frequency associated with the dynamics of the system confir ming that classical resonance is responsible for CR. We also classify the d ifferent routes via which CR can originate. The ability to manipulate the r oute to CR can be of importance in developing technological applications.
