摘要

We investigate signal transmission and amplification in a network of n bistable oscillators that are bidirectionally coupled with two distinct coupling strengths. In this set-up, only the first oscillator is directly driven by a weak sinusoidal signal, while the others interact solely through the coupling mechanism. Our results demonstrate that selecting appropriate combinations of the coupling strengths can significantly enhance the efficiency of signal propagation and amplification across the network. Additionally, each oscillator exhibits nonlinear resonance due to the asymmetric nature of the interactions. To further examine the system’s dynamics, we introduce a high-frequency force to the first oscillator. This additional excitation induces vibrational resonance throughout the network, further boosting its capacity to transmit and amplify signals. To provide a comprehensive view of the propagation mechanism, we map the regions of coupling strength combinations that facilitate effective signal transfer from the first to the last oscillator. This study highlights the impact of nonlinear and vibrational resonance on enhancing signal dynamics, with potential applications in signal processing, energy transfer and coupled oscillator networks.
