Efficient Computation of Extended Surface Sources
William W. Symes
Source extension is a reformulation of inverse problems in wave propagation, that at least in some cases leads to computationally tractable iterative solution methods. The core sub…

Wavefield Reconstruction Inversion: an example
William W. Symes
Nonlinear least squares data-fitting driven by physical process simulation is a classic and widely successful technique for the solution of inverse problems in science and engineer…
