Outpost Method of Computing Leaking and Normal Modes for Elastic Multilayered Half-space

Accurate computation of leaky modes for anomalous layered models

“…For models typically with high Poisson's ratios such as that shown in Table 1, leaky waves may show significant energy on the seismogram recorded at proper distances [Roth et al 1998, Gao et al 2014. Dispersion analysis in terms of mode theory would then afford complementary information for seismic surveying, especially for inverting the P-wave velocity structure [Oliver 1964, Su and Dorman 1965, Znak and Kashtan 2015 due to it being better sensed by leaky modes than by shear normal modes. Therefore, accurate computation of leaky modes is necessary, as done here, for it may also have great implications for high-resolution seismic surveying and full waveform inversions [Roth et al 1998].…”
