Physical Sensors Based on Lamb Wave Resonators [PDF]

open access: yesMicromachines
A Lamb wave is a guided wave that propagates within plate-like structures, with its vibration mode resulting from the coupling of a longitudinal wave and a shear vertical wave, which can be applied in sensors, filters, and frequency control devices.
