Modeling linear Rayleigh wave sound fields generated by angle beam wedge transducers
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 ...

Rayleigh Waves in a Rotating Orthotropic Micropolar Elastic Solid Half-Space
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.

Rayleigh-wave coupling to atmospheric compression waves* [PDF]
AbstractThe theory of dispersive Rayleigh waves coupled to atmospheric compressional waves is derived for the case of a solid surface layer. Numerical computation of phase and group velocity curves indicates that an additional branch may be introduced to the dispersion curves as a result of air coupling.

High-temperature high-sensitivity AlN-on-SOI Lamb wave resonant strain sensor
A piezoelectric AlN-on-SOI structured MEMS Lamb wave resonator (LWR) is presented for high-temperature strain measurement. The LWR has a composite membrane of a 1 μm thick AlN film and a 30 μm thick device silicon layer.

The axisymmetric Rayleigh waves in a semi-infinite elastic solid
: It is well-known that Rayleigh wave, also known as surface acoustic wave (SAW), solutions in semi-infinite solids are plane waves with signatory properties like the distinct velocity and exponentially decaying deformation in the depth.

Study of high-resolution analysis of Rayleigh waves on the basis of the Choi–Williams distribution
Rayleigh wave exploration is widely used in the field of engineering investigation, which can analyze the near surface velocity structure. However, the traditional Rayleigh wave exploration data processing method can only provide the average change of ...

Resonance Expansions and Rayleigh Waves [PDF]
The author studies expansions of solutions of the wave equation in a compact set with initial data supported in the same set. He considers the general framework of the ``black box scattering'' introduced by Sjöstrand and Zworski. In particular, this includes the classical case of scattering by obstacle with Dirichlet or Neumann boundary conditions and ...

Disturbances of surface wave field due to wave scattering at shallow cavities
In homogenous half spaces, the wave fields at shallow depth are dominated by Rayleigh waves activated by the surface sources. When the forward Rayleigh waves encounter a shallow cavity, the displacement shapes and the particle orbit are changed. Rayleigh
