We report measurements of synchronization in two nanomechanical beam oscillators coupled by a mechanical element. We charted multiple regions of frequency entrainment or synchronization by their corresponding Arnold's tongue diagrams as the oscillator was driven at subharmonic and rational commensurate frequencies. Demonstration of multiple synchronized regions could be fundamentally important to neurocomputing with mechanical oscillator networks and nanomechanical signal processing for microwave communication.
我们报告了通过一个机械元件耦合的两个纳米机械梁振荡器中的同步测量结果。当振荡器在亚谐波和有理 commensurate 频率下被驱动时，我们通过它们相应的阿诺德舌图绘制了多个频率夹带或同步区域。多个同步区域的证明对于使用机械振荡器网络的神经计算和用于微波通信的纳米机械信号处理可能具有根本重要性。
