Shear wave generation using a spiral electromagnetic acoustic transducer [PDF]
, 2006 A spiral electromagnetic acoustic transducer (EMAT) is efficient in eddy current generation and has been used for surface defect inspection using Rayleigh waves or thickness gauging based on plane waves in echo mode.

Noise generation in the solid Earth, oceans, and atmosphere, from non-linear interacting surface gravity waves in finite depth [PDF]
, 2012 Oceanic pressure measurements, even in very deep water, and atmospheric pressure or seismic records, from anywhere on Earth, contain noise with dominant periods between 3 and 10 seconds, that is believed to be excited by ocean surface gravity waves. Most

Rayleigh wave nonlinearity [PDF]
The Journal of the Acoustical Society of America, 1993 The elastic nonlinearity in Rayleigh waves is investigated theoretically. Studies have revealed that nonlinearity in Rayleigh waves involves nonlocal as well as local effects [Parker and Talbot, J. Elast. 15, 389 (1985)]. Finite amplitude effects on sound in fluids are entirely local, and the effects on different wavelets are therefore independent.

Efficiency of Higher Order Finite Elements for the Analysis of Seismic Wave Propagation [PDF]
, 2000 The analysis of wave propagation problems in linear damped media must take into account both propagation features and attenuation process. To perform accurate numerical investigations by the finite differences or finite element method, one must consider ...

Modeling linear Rayleigh wave sound fields generated by angle beam wedge transducers
AIP Advances, 2017 In this study, the reciprocity theorem for elastodynamics is transformed into integral representations, and the fundamental solutions of wave motion equations are obtained using Green’s function method that yields the integral expressions of sound beams ...

Magnetoelastic Rayleigh wave convolver
Applied Physics Letters, 1975 An epoxy−bonded LiNbO3−YIG−LiNbO3 composite structure has been constructed and operated as a magnetoelastic Rayleigh wave convolver with 50−MHz input signals. The acoustic signals were propagated on a (110) YIG surface and the convolution characteristics were studied as a function of the magnitude and direction of the applied magnetic field. Nonuniform

Rayleigh Waves in a Rotating Orthotropic Micropolar Elastic Solid Half-Space
International Journal of Geophysics, 2013 A problem on Rayleigh wave in a rotating half-space of an orthotropic micropolar material is considered. The governing equations are solved for surface wave solutions in the half space of the material.
