Notes:
Wave field extrapolation including critical angle events in modeling, migration and inversion can be handled with algorithms based on both the one-way wave equations and the two-way wave equation. It is shown that for 1-D inhomogeneous media, critical angle events as well as multiple reflections may elegantly be included in pre-stack modeling, pre-stack migration and velocity inversion. For 2-D and 3-D inhomogeneous media a powerful pre-stack migration scheme can be developed which includes critical angle events as well as multiple reflections. Finally, suggestions for practical applications are given.
