Immersive boundary conditions: Theory, implementation, and examples

F Broggini, M Vasmel, JOA Robertsson, DJ van Manen - Geophysics, 2017 - library.seg.org
Many applications in computational geophysics involve the modeling of seismic wave
propagation on a set of closely related subsurface models. In such scenarios, it is of interest …

Free-surface elastic wave injection and wavefield reconstruction with applications to elastic reverse time migration

B Han, XB **e - Geophysics, 2023 - library.seg.org
Accurately injecting and extrapolating multicomponent seismic data is a major step in elastic
reverse time migration (RTM) and full-waveform inversion. The theoretical basis of this …
