Eigenwaves: Finite-frequency Eigenrays in Elastic Anisotropic Media
Zvi Koren
The Eigenray method solves two-point boundary-value ray-tracing problems in heterogeneous anisotropic elastic media using a variational formulation based on the eikonal equation. H…

Theoretical Framework for Phase-space Local-Angle-Domain Waveform Inversion in Anisotropic Elastic Media
Zvi Koren
We present a phase-space formulation of elastic full-waveform inversion (FWI) based on local-angle-domain (LAD) representations of seismic scattering. Instead of minimizing acquisi…
