Study on the Boundary Problem for the Numerical Modeling by the Convolution Differentiator Method
This paper introduces perfect match layer (PML) absorbing boundary which was added on the boundary of the interesting region, no reflection is produced when wave propagates from boundary of studied region to absorbing layer and wave attenuates exponentially with propagation distance. By building different models and modeling, the numerical experiments demonstrate that the PML absorbing boundary can better resolve the boundary reflecting problems, Superiority of PML boundary condition was validated.
