Influence of viscoelasticity and interfacial slip on acoustic wave sensors [PDF]

, 2000
Acoustic wave devices with shear horizontal displacements, such as quartz crystal microbalances (QCM) and shear horizontally polarised surface acoustic wave (SH-SAW) devices provide sensitive probes of changes at solid-solid and solid- liquid interfaces.

Influence of Waterproof Films on the Atomization Behavior of Surface Acoustic Waves

Micromachines, 2019
One of the reasons why commercial application of surface acoustic wave (SAW) atomization is not possible is due to the condensation of aerosol droplets generated during atomization, which drip on the interdigitated transducer (IDT), thereby causing ...

Surface acoustic wave propagation in monolayer graphene

, 2009
Surface acoustic wave (SAW) propagation is a powerful method to investigate 2D electron systems. We show how SAW observables are influenced by coupling to the 2D massless Dirac electrons of graphene and argue that Landau oscillations can be observed as ...
