Comparison of quasi-Rayleigh waves and Rayleigh waves, and clarifying the cut-off frequency of quasi-Rayleigh waves

Ultrasonics, 2019
The Partial Wave Method is unique in that it establishes a foundation on which various elastodynamic guided waves can be compared. In this paper, the method is used to compare quasi-Rayleigh waves and Rayleigh waves, and investigate the eccentricities of the Partial Wave Method at phase velocities equal to the Rayleigh wave speed.

Wave gradiometry for USArray: Rayleigh waves

Journal of Geophysical Research: Solid Earth, 2009
Wave 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

Nonlinear magnetoelastic Rayleigh waves

Journal of Magnetism and Magnetic Materials, 1994
Abstract The propagation of nonlinear magnetoelastic waves in a semi-infinite ferromagnetic single crystal has been investigated. We consider the nonlinearity of magnetic origin and find the dispersion relation of coupled nonlinear magnetostatic and elastic Rayleigh waves. We present the results of a theoretical study of dispersion and attenuation of

Rayleigh Wave Tomography

1991
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 ...
