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.

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.

Internal wave instability: Wave-wave versus wave-induced mean flow interactions
Physics of Fluids, 2006In continuously stratified fluid, vertically propagating internal gravity waves of moderately large amplitude can become unstable and possibly break due to a variety of mechanisms including (with some overlap) modulational instability, parametric subharmonic instability (PSI), self-acceleration, overturning, and convective instability.

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 ...

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.

Forward and Inverse Scattering Algorithms based on Contrast Source Integral Equations, 2018
This chapter examines solutions to the Maxwell equations in a vacuum: monochromatic plane waves and their polarizations, plane waves, and the motion of a charge in the field of a wave (which is the principle upon which particle detection is based).

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 .

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 ...

Wave-Wave Coupling in Ion Wave Propagation
Journal of the Physical Society of Japan, 1970In the propagation of two ion waves (frequencies f1 and f2) the signal of f1 − f2 is found to grow spacially in some region, contrary to the monotonic damping of the waves of f1 and f2, which is explained as a wave-wave coupling among ion waves.

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.
