Design and fabrication of a SIO2/ST-cut quartz love mode surface acoustic wave transducer for operation in liquid media [PDF]
, 2000 Love mode surface acoustic wave (SAW) transducers were designed and fabricated by depositing silicon dioxide on a ST-cut quartz crystal wafer using r.f. magnetron sputtering. Two different propagation directions have been investigated by aligning the SAW

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges
River Research and Applications, EarlyView.ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Controlling surface acoustic waves (SAWs) via temporally graded metasurfaces
Journal of Sound and VibrationIn this manuscript, the temporal rainbow effect for surface acoustic waves (SAW) is illustrated through a temporal analog of space metagradings. We show that a time-modulated array of mechanical resonators induces a wavenumber-preserving frequency transformation which, in turn, dictates Rayleigh-to-Shear wave conversion. The process is unfolded through
