The rising need for hybrid physical platforms has triggered a renewed interest for the development of agile radio-frequency phononic circuits with complex functionalities. The comb…
Acoustic radiation-free surface phononic crystal resonator for in-liquid low-noise gravimetric detection
Feng Gao, Amine Bermak, Sarah Benchabane +2
Acoustic wave resonators are promising for gravimetric biosensing. However, they generally suffer from strong acoustic radiation in liquid, which limits their quality factor and in…
Nonlinear effects in locally-resonant nanostrip phononic metasurface at GHz frequencies
Feng Gao, Amine Bermak, Sarah Benchabane +2
In this paper, we report on the observation of nonlinear effects in a nanostrip phononic metasurface (NPM) that enable the tuning of resonance frequencies at 1.42 GHz. The NPM reso…
