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 ...
Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations
(Elsevier, 2017)
We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...
Asymptotic approach for the nonlinear equatorial long wave interactions
(2011-08-30)
In the present work we use an asymptotic approach to obtain the long wave equations. The shallow water equation is put as a function of an external parameter that is a measure of both the spatial scales anisotropy and the ...

Low-dimensional chaos and wave turbulence in plasmas
(ROYAL SOC, 2008)
We investigated drift-wave turbulence in the plasma edge of a small tokamak by considering solutions of the Hasegawa-Mima equation involving three interacting modes in Fourier space. The resulting low-dimensional dynamics ...
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 ...
