- W2109456546 abstract "Summary One-way wave equation method is very efficient. It can be used as forward and backward propagators in seismic modeling and migration. However, unlike the full wave method, the one-way method is usually derived for a source free situation. The source is added to the calculation as a boundary condition. The free surface effect at both the source side and receiver side are often not considered. Based on the plane wave decomposition, this study gives a free surface and source condition for elastic one-way wave equation method. This boundary condition can be applied at either the source side or the receiver side. With this boundary condition, many of the free surface effects, e.g., reflected P and S-waves, secondary surface waves, etc., can be generated. This boundary condition can be easily applied to reflection, VSP and cross hole modelings and seismic migration. It is especially useful for one-way methods based on the wavenumber domain Fourier transforms." @default.
