A fast method of computing group-velocity partial derivatives for Love waves propagating in a layer on a half-space
(1999)
The dispersion relation for Love waves in a layer on a half-space is modified by introducing the wave number and its square instead of the phase velocity. The implicit function theorem is then used to derive the analytical ...
Analytical partial derivatives of the phase- and group Velocities for rayleigh waves propagating in a layer on a half-space
(2005)
The dispersion relation for Rayleigh waves in a layer on a half-space is modified by
introducing the quadratic wave number instead of the phase velocity. The implicit
function theorem is then used to derive analytical ...
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 ...
An integrable evolution equation for surface waves in deep water
(Iop Publishing Ltd, 2014-01-17)
In order to describe the dynamics of monochromatic surface waves in deep water, we derive a nonlinear and dispersive system of equations for the free surface elevation and the free surface velocity from the Euler equations ...
A panel-Fourier method for free-surface flows
(ASME Amererican Society of Mechanical Engineering, 2000-12)
A panel-Fourier method for ship-wave flow problems is considered here. It is based on a three-dimensional potential flow model with a linearized free surface condition, and it is implemented by means of a low order panel ...
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 ...
Interaction between wave and coastal structure: Validation of two lagrangian numerical models with experimental results marine 2011
(2011-12-01)
Numerical modeling of the interaction among waves and coastal structures is a challenge due to the many nonlinear phenomena involved, such as, wave propagation, wave transformation with water depth, interaction among ...
