Green-Naghdi dynamics of surface wind waves in finite depth
(2018-02-08)
The Miles' quasi laminar theory of waves generation by wind in finite depth h is presented. In this context, the fully nonlinear Green-Naghdi model equation is derived for the first time. This model equation is obtained ...
Surface acoustic waves in interaction with a dislocation
(ELSEVIER, 2010)
A surface acoustic wave can interact with dislocations that are close to the surface. We characterize this
interaction and its manifestations as scattered surface acoustic waves for different orientations with
respect ...
Evolution equation for short surface waves on water of finite depth
(Elsevier B.V., 2009-08-15)
We address the question of determining the evolution equation for surface waves propagating in water whose depth is much larger than the typical wavelength of the surface disturbance. We avoid making the usual approximation ...
Surface gravity waves on randomly irregular floor and the telegrapher's equation
(American Institute of Physics, 2021-04)
The simplest model for the evolution of the mean-value of a surface gravity wave propagating in a random bottom has been connected with the telegrapher's equation. This analysis is based on the comparison of the mean-value ...
Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves
(Elsevier Science, 2019-02)
The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D ...
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 ...
Numerical study of the spectral 3-D Green's function singularities for piezoelectric SAW components
(2005)
This article deals with the numerical study of the singularities appearing in the spectral 3-D Green's function associated with the piezoelectric surface acoustic wave components (so-called SAW components). These electrical ...
