Propagation of Rayleigh-Waves on a Spherical Surface

Propagation of coupled Rayleigh-gravity waves on the ocean floor

It is shown that the Ocean-Earth crust interface can propagate gravity-sound Rayleigh waves. Dispersion properties of waves and flux of energy are derived. It is shown that the waves split into low and fast velocity branches. The fast branch has a multimode structure and has a cutoff in frequency and wave number. Numerical solutions are discussed.

Effect of spherical aberration and surface waves on propagation of lens-coupled terahertz pulses.

Spatiotemporal measurements of a near-single-cycle terahertz pulse emitted from a photoconductive switch terahertz (THz) source show the effects of spherical aberration and surface waves on the pulse shape. The measured phase front has a swallow-tail shape described by catastrophe theory that contributes to the concentric ring structure of THz beam profiles. A time-of-flight model shows that th...

Rayleigh Waves in a Homogeneous Magneto-Thermo Voigt-Type Viscoelastic Half-Space under Initial Surface Stresses

This paper deals with the propagation of magneto-thermo Rayleigh waves in a homogeneous viscoelastic half-space under initial stress. It has been observed that velocity of Rayleigh waves depends on viscosity, magnetic field, temperature and initial stress of the half-space. The frequency equation for Rayleigh waves under the effect of magnetic field, stress and temperature for both viscoelastic...

Source and Propagation Effects of Rayleigh Waves From

A reference point equalization method has been developed which enables 'the separation of source and propagation effects of surface waves. The method works on seismic events located in a small source region, which allows us to assume that all events share the same path effects to a given receiver. Two important steps in the method are initialization and iteration. Initialization obtains the fir...
