Type-III intermittency in a coupled nonlinear LCR circuit

Type-III intermittency is experimentally observed in an electronic device. Experimental circuit is considered to be a two-coupled identical oscillator system. Each oscillator consists of an inductor, a resistor and a diode connected in series and is coupled through an inductor. Intermittency takes place in narrow region where the synchronized motion between two oscillators just breaks up. Waveform, maps and power spectrum of intermittent behavior are studied in this paper. Experimental results are compared with those of a numerical calculation based on the equations for this circuit with observed nonlinear characteristics of diode. Good agreements between experiment and numerical calculation are obtained.
