Rayleigh phase
WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to … WebJan 1, 2024 · As expected, the transmission properties of Rayleigh waves are dependent on the phase shift of the structures, which can be employed to manipulate Rayleigh wave propagation. In the symmetric case (ϕ = 0), we can observe a Bragg gap in the range of 0.43 to 0.53 MHz as shown in Fig. 5 (a).

WebSUMMARY We obtained phase velocities of fundamental Rayleigh waves in the northwestern Pacific ocean and the northern Philippine sea from seismograms retrieved from a long-term broad-band ocean bottom seismometer (LT-OBS) array deployed in 1999‐2000 and from those recorded in Japan, Guam and Ponape islands. This array … WebThe latter was calculated previously as the Rayleigh phase velocity sensitivity. The resulting sensitivity kernels for each inversion input data, i.e. phase velocity, group velocity and its ...
WebHowever, Rayleigh scattering causes the transmitted wave to be out of phase with the free-space (initial) wave. The light is scattered many times as it travels through the medium. … WebThe Rayleigh wave shows a clear phase shift between the radial (q 0) and vertical (w 0) components and is much larger than the body-wave arrivals. The experimental result …
