Near field enhancements from angled surface defects : a comparison of scanning laser source and scanning laser detection techniques [PDF]

, 2011
Enhancement of the Rayleigh wave signal amplitude at a surface defect, due to interference of incident, reflected and mode converted waves, has been reported by several authors, and it has been suggested that this could be used as a fingerprint of the ...

Contactless Viscosity Sensor Using Surface Acoustic Waves and Light Scattering

, 2015
Surface acoustic wave (SAW) is a form of an acoustic wave of nano-meter amplitude travelling along the surface of an elastic material. Recently, SAW devices have shown promising application in fluid actuation for microfluidics.
