Surface acoustic wave microfluidics [PDF]
Lab on a Chip, 2013 The recent introduction of surface acoustic wave (SAW) technology onto lab-on-a-chip platforms has opened a new frontier in microfluidics. The advantages provided by such SAW microfluidics are numerous: simple fabrication, high biocompatibility, fast fluid actuation, versatility, compact and inexpensive devices and accessories, contact-free particle ...

Dispersion of surface acoustic waves in thin films at extreme wavelength-to-thickness ratios [PDF]
JASA Express Letters, 2022 Surface acoustic waves (SAWs) are sensitive to the presence of a layer on the surface of a material, even if this layer is extremely thin compared to their wavelengths. Given the very slow propagation velocities of SAWs compared to electromagnetic waves,

Bending and splitting of spoof surface acoustic waves through structured rigid surface
Results in Physics, 2018 In this paper, we demonstrated that a 90°-bended imaging of spoof surface acoustic waves with subwavelength resolution of 0.316λ can be realized by a 45° prism-shaped surface phononic crystal (SPC), which is composed of borehole arrays with square ...

Large-scale numerical modeling of hydro-acoustic waves generated by tsunamigenic earthquakes [PDF]
Natural Hazards and Earth System Sciences, 2015 Tsunamigenic fast movements of the seabed generate pressure waves in weakly compressible seawater, namely hydro-acoustic waves, which travel at the sound celerity in water (about 1500 m s−1).
