Dispersion-Guided Physics-Aware Deep Inverse Operator for Surface Wave Mode Separation
Yang Cui, Sujith Swaminadhan, Yangkang Chen +2
Surface-wave (SW) dispersion analysis is widely used in near-surface geophysics and seismology to determine shear-wave velocity structures by measuring SW geometric dispersion in s…
