High-overtone Bulk-Acoustic Resonator gravimetric sensitivity: towards wideband acoustic spectroscopy

, 2015
In the context of direct detection sensors with compact dimensions, we investigate the gravimetric sensitivity of High-overtone Bulk Acoustic Resonators, through modeling of their acoustic characteristics and experiment. The high frequency characterizing

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry

Advanced Materials Interfaces, EarlyView.
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Fluid-loaded metasurfaces

, 2017
We consider wave propagation along fluid-loaded structures which take the form of an elastic plate augmented by an array of resonators forming a metasurface, that is, a surface structured with sub-wavelength resonators.
