文摘
- •
Coupled non-oscillatory Rayleigh–Duffing oscillators bifurcate into periodic oscillations.
- •
Direct or difference coupling nullify internal linear damping to produce oscillation.
- •
Higher coupling leads to quasi-periodic, chaotic and stable periodic oscillations.
- •
Different dynamical states are examined by numerical and analytical means.
- •
Low RF and microwave frequency experiments confirm predicted dynamics of coupled system.
