Although a higher-order mode was recently used (Wang et al., 2024), the mode most extensively applied during Rayleigh … WebZigzag dispersion curves are sometimes found in Rayleigh wave exploration when the media contain low velocity layers. The zigzag dispersion curves are believed to have a relationship with low velocity layers. Especially, there is a relationship between ‘jump point' frequencies of zigzag dispersion curves and the parameters of the media. So the jump …
