研制了一种与三个局域机械谐振器弱连接的机电声子波导。由强压电激励引起的非线性弹性效应使得波导中的声波能够被传递到空间上不同的谐振器。调整非线性调制的频率使得能够通过将声波从波导切换到目标谐振器来选择性地驱动目标谐振器。经由声子波导远程控制多个机械谐振器的能力开启了声子网络的可能性，在声子网络中，声波可以被引导到分布式子谐振器。开发了一种弱连接到三个局域机械谐振器的机电声子波导。由强压电激励引起的非线性弹性效应使得波导中的声波能够被传递到空间上不同的谐振器。调整非线性调制的频率使得能够通过将声波从波导切换到目标谐振器来选择性地驱动目标谐振器。经由声子波导远程控制多个机械谐振器的能力开辟了声子网络的可能性，在该声子网络中，声波可以被引导到分布式子系统。
An electromechanical phonon waveguide that is weakly connected to three localized mechanical resonators is developed. A nonlinear elastic effect induced by intense piezoelectric excitation enables acoustic waves in the waveguide to be transferred to the spatially distinct resonators. Adjusting the frequency of the nonlinear modulation enables a target resonator to be selectively driven by switching the acoustic wave from the waveguide to it. The ability to remotely control multiple mechanical resonators via the phonon waveguide opens up the possibility of a phonon network in which acoustic waves can be guided to distributed sub-systems.An electromechanical phonon waveguide that is weakly connected to three localized mechanical resonators is developed.
