Linear and nonlinear interactions in surface acoustic wave driven phononic resonators
Résumé
We propose to exploit the interaction between surface acoustic waves (SAW) and
locally-resonant phononic resonators toachieve coherent driving of
micro- nano-mechanical resonators with SAW and, reciprocally, to control
SAW propagation at a deep sub-wavelength scale. We investigate the
proposed physical system both in the linear and non-linear regimes and
reveal the occurrence of Duffing-like nonlinearities and of non-linear
coupled mechanical states in the 100-MHz frequency range.
