ABSTRACT

In modeling and migration based on wave equation, the wavefield has to be extrapolated in a finite domain due to the limitations of our survey and computers. Absorbing boundary conditions must be introduced, otherwise some reflections will occur at the artificial grid boundary. In this paper, I will introduce an absorbing boundary condition based on the one-way wave equation, with some numerical examples.
