Zero-Group-Velocity acoustic waveguides for high-frequency resonators

open access: yes, 2017
The propagation of the Lamb-like modes along a silicon-on-insulator (SOI)/AlN thin supported structure was theoretically studied in order to exploit the intrinsic zero group velocity (ZGV) features to design electroacoustic resonators that do not require
