Studies on Dynamics of Driven Bilaterally Coupled Gunn Oscillator

The dynamics of bilaterally coupled Gunn oscillator driven by external periodic signal has been examined through numerical simulation and experimental observation. The coupling factors between the two oscillators in either path as well as the strength and frequency of the external periodic driving signals are key parameters to control the dynamics of Driven Bilaterally Coupled Gunn Oscillator (DBCGO) system. The numerical study explores the possibility of generation of controllable chaotic signals in DBCGO system. The present work also considers this method through a hardware experiment. For different set of coupling factors, driving signal strength and frequencies, chaotic oscillations are observed. Therefore, the DBCGO system with suitable couplings and driving signal conditions can be considered as a potential source of chaotic signals in microwave frequency range.
