Perfect Matched Layer Optimization For Acoustic Wave Modelling

The Perfect Matched Layer (PML) method is presented and optimized. It is shown that the implemented optimization increases the effectiveness of the absorbing layer. Furthermore, PML’s effectiveness is analyzed with respect to its defining constants. Such analysis allows for faster tuning of PML to any given setup. Further results show that side effects are very sensitive to the number of grid points used in the absorbing layer, with better results found for wider layers.
