Figure 1. (A) Frame-based Gaussian beam decomposition. Initial wave fields are
decomposed into Gaussian windowed beam components that are then launched at
different angles into the medium. (B) Example of the backpropagation of a single
Gaussian beam with a low-frequency initial beam width of 30 km for a
pPp phase for the model shown in
Figure 2.
