Surface Acoustic Wave Focusing and Induced Rayleigh Waves
Physical Review Letters, 1995We introduce a new method for observing the anisotropic propagation of surface acoustic waves on solids. Point source and point detection of ultrasonic waves, scanned as a function of propagation angle, give the group velocities and intensities of Rayleigh and pseudosurface waves.

In an elastically isotropic semiinfinite medium having a free surface with a weak harmonic corrugation, the interaction between the Rayleigh wave guided along the free surface and the shear vertical and pressure bulk elastic waves propagating in the substrate is investigated for the propagation directions lying in a plane perpendicular to the average ...

Pulsed nonlinear Rayleigh waves
The Journal of the Acoustical Society of America, 1994Pulsed, plane, nonlinear Rayleigh waves in isotropic solids are investigated with numerical solutions of the coupled spectral equations derived by Zabolotskaya [J. Acoust. Soc. Am. 91, 2569 (1992)]. Calculations of waveform evolution are presented as functions of distance from the source and depth within the solid.

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.

In modern Rayleigh-wave devices, transducers are needed to generate Rayleigh waves in response to an applied electrical signal and to sense the waves so as to give an electrical output waveform. These are clearly key requirements for electronic devices, and are usually met by using interdigital transducers on piezoelectric substrates.

It is now a century since LORD RAYLEIGH published his theoretical proof of the existence of elastic waves propagating along the plane surface of an elastic solid [1]. In reading this paper one is struck by the fact that, except for minor changes in notation, the formulation established by Rayleigh is still followed today in the theory of elastic guided

The Yoffe crack model [I] considers a crack of fixed length propagating with constant speed in an infinite plate under a uniform tensile stress normal to the crack plane. It is assumed that the crack retains its original length during propagation by resealing itself at the trailing end. For this problem the strain energy release rate G is given by $

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.
