Under special kinematic conditions helium atoms impinging upon a crystal surface can be inelastically trapped into a surface bound state and ride the created Rayleigh wave. This special case of phonon-assisted selective adsorption, leading to an atom-phonon bound state (atomic polaron), can explain previously unassigned resonant features observed in ...

Rayleigh Waves on Curved Surfaces
The Journal of the Acoustical Society of America, 1969Rayleigh waves, which are elastic surface waves occurring at the interface between a solid elastic body and vacuum, are investigated. The exact solution of some canonical elastodynamic problems in a circular cylindrical geometry is given, from which the Rayleigh wave contribution is isolated.

A note on thermoelastic rayleigh waves
Journal of the Mechanics and Physics of Solids, 1961Abstract The propagation of waves on the surface of an elastic thermally conducting medium, which has been the subject of two recent papers, is re-examined herein, and expressions are displayed which exhibit the frequency dependence of the phase velocity and amplitude attenuation.

Localization of Rayleigh waves
Physical Review B, 2000We study the localization of Rayleigh waves propagating in a semi-infinite and isotropic medium with inhomogeneities that are modeled as rods parallel to the incoming wave front and are distributed randomly up to a maximum depth. For a perfectly smooth surface, the localization length of a Rayleigh wave is predicted to reach a minimum at intermediate ...

Tomographic imaging involves the collection of data from a series of projections through an object, and the reconstruction of variations in a chosen parameter across a two-dimensional section. It is now an established method for the reconstruction of images from ultrasonic data, and has been used widely in such areas as medical ultrasound and non ...

The soliton of the Rayleigh wave
Physics Letters A, 1988Abstract A theory of self-induced transparency is constructed for the Rayleigh wave in a system which consists of a thin resonance transitional layer on a solid surface. The solution is obtained in the form of a soliton (2π-pulse of McCall and Hanh) for the Rayleigh wave.

Wave gradiometry for USArray: Rayleigh waves
Journal of Geophysical Research: Solid Earth, 2009Wave gradiometry (WG) is a new array data processing technique to extract phase velocity, wave directionality, geometrical spreading, and radiation pattern from spatial gradients of waveforms. A weighted inversion method and a reducing velocity method are introduced to compute spatial gradients accurately for irregular arrays. Numerical experiments are

The Caustic of a Rayleigh-Wave
1989The method of caustic or shadow-spot technique is utilized to determine the caustic of a Rayleigh-wave. The size and shape of the caustic allow for characterization of the source of the Rayleigh-wave disturbance .

In this chapter, the mechanism for generating fluctuating reservoir pressures will be explored. The generation of surface waves and fluctuating pressures in the upstream reservoir due to gate motion will be examined. The energy input into surface waves is dissipated, or dispersed, as the waves travel away from the structure.
