Different methods for handling the corner reflections of absorbing boundary condition in the numerical simulation of seismic waves

摘要

In numerical simulation of wave equation, in a limited area to establish artificial boundary absorbing boundary conditions, the angular point on the calculation area of the processing is also cannot ignore a problem. According to CE, MTF, PML three different boundary conditions, using different angular point processing method, and through the numerical example comparing with different methods, better numerical results in practical application.
