Abstract Conventional models of the structure of the Earth, such as the Preliminary Reference Earth Model (PREM), assume a bonded interface between the crust and the upper mantle. The bonded contact model is consistent with the observation of Love waves during an earthquake.

Ergodicity in wave-wave diffraction
Journal of Physics A: Mathematical and General, 1999Summary: Ray propagation over long distances through a sinusoidal volume grating, where the refractive index varies perpendicular to the direction of incidence, is characterized by a proliferation of caustics. These dominate the distribution of directions (momentum density) of emerging rays.

Wave–Particle and Wave–Wave Interactions
2012In Chap. 3 we have discussed how plasma responds to an external (weak) electromagnetic perturbation, which results in a specific wave dispersion and damping. This damping is linear, i.e., proportional to the wave amplitude and there is no change in the plasma distribution function other than small oscillations proportional to the wave amplitude ...

Physics Letters A, 1980
Abstract The adiabatic invariant or wave action A for waves propagating in a slightly inhomogeneous medium is considered for the case of drift wave in a magnetized plasma. It is found that A = W, where W is the energy density, instead of the familiar expression W ω .

Waves, amplitude waves, intensity waves
Journal of Optics, 1991The interference of two or more waves give rise, at intensity level, to another wave phenomenon, a second-order wave structure. The interference of different frequency waves is the frame in which this fact becomes most evident. A theoretical treatment of the interference of two homogeneous plane waves of different frequencies is given.

SOLITARY WAVE INTERACTIONS WITH CONTINUOUS WAVES
International Journal of Bifurcation and Chaos, 2006Solitary wave propagation under interaction with continuous waves is studied in the context of the Nonlinear Schrödinger Equation. An analytical approach, based on the conserved quantities of the wave evolution, is used to study transverse velocity variations for the case of nonzero transverse wavenumber difference between the solitary and continuous ...

Magnetohydrodynamic Waves in Wave Guides
The Physics of Fluids, 1959Propagation of magnetohydrodynamic waves is investigated in a fluid bounded by a cylindrical surface of constant, but not necessarily circular, cross section. The fluid is assumed to be nonviscous and perfectly conducting with a constant magnetic field applied parallel to the walls of the cylinder.

Nonlinear wave-wave interactions and wedge waves
Chinese Journal of Oceanology and Limnology, 2005A tetrad mechanism for exciting long waves, for example edge waves, is described based on nonlinear resonant wave-wave interactions. In this mechanism, resonant interactions pass energy to an edge wave, from the three participating gravity waves. The estimated action flux into the edge wave can be orders of magnitude greater than the transfer fluxes ...

Bispectra of wind-waves and wave-wave interaction
Journal of Oceanography, 1977Bispectra of wind-waves in wind tunnels were calculated in order to understand the characteristics of the nonlinear wave-wave interaction in actual wind-wave field. It is shown that the nonlinearity in wind-waves increases in magnitude with the development of wind-waves and that the characteristics of nonlinearity in wind-waves in the early stage of ...
