WebThe relationship between Rayleigh-wave phase velocity and frequency has been widely utilized to estimate the S-wave velocities in shallow layers using the multichannel analysis of surface waves (MASW) technique. Hence, Rayleigh wave is a main focus of most near-surface seismic studies. Conventional dispersion analysis of Rayleigh waves assumes ... Web2 days ago · To manipulate wave propagation, periodic structures have been widely investigated since Lord Rayleigh theoretically analysed vibrations on a fine string [21]. When quantum or classical waves pass through periodic structures with defects, the wave is typically localised around the defect, and an additional transmission can be observed in …
WebMar 3, 2024 · Rayleigh-wave ellipticity polarization, or horizontal-to-vertical spectral ratio (H/V), is particularly sensitive to shallow earth model parameters (e.g., shear wave velocity). We propose a novel Rayleigh-wave H/V inversion method to delineate near-surface strong-velocity-contrast structures. In the new inversion method, the shear wave velocity model … WebFIG. 3. The Rayleigh wave generated from the wavelet in Figure 2 when applied to the surface of a body with a constant 1000 m/sec shear velocity. After the first break energy peels off at the pressure wave velocity of 2000 m/sec (marked by the red line), the Rayleigh wave propagates
