Spatial-temporally resolved high-frequency surface acoustic waves on silicon investigated by femtosecond spectroscopy
(American Institute Of Physics, 2012-06)
Various types of surface acoustic waves are generated by femtosecond pulses on bulk silicon with aluminium stripe transducers. Rayleigh and leaky longitudinal surface acoustic wave modes are detected in the time domain for ...
Infragravity wave energy partitioning in the surf zone in response to wind-sea and swell forcing
(MDPI AG, 2019)
An alongshore array of pressure sensors and a cross-shore array of current velocity and
pressure sensors were deployed on a barred beach in southwestern Australia to estimate the relative
response of edge waves and leaky ...
Ultrasound imaging of immersed plates using high-order Lamb modes at their low attenuation frequency bands
(2017-11-01)
This paper focuses on the use of a Lamb wave-based methodology for ultrasound imaging of immersed plate structures. In these cases Lamb waves can be strongly attenuated due to leaky waves and viscous losses in the liquid, ...
Flow estimation in a steel pipe using guided waves
(2016-09-30)
In this investigation, a flow rate estimation guided wave based scheme in pipes is
proposed. The effect of the fluid over the propagation of longitudinal waves has been
experimentally studied by using several laminar ...
Uso das ondas de Lamb e Scholte para caracterização de líquidos
(Universidade Estadual Paulista (Unesp), 2015-05-29)
The study of the interaction of elastic waves in solids immersed in a fluid has been recognized as a suitable method for fluid characterization. Guided waves in plate-like structures, are mul- timodal and dispersive. These ...
