Dear @zhangxiaoshuotttt,
A PML thickness of 4 gridpoints (FW=4) is far too small. Typically, I use a FW = 20 or larger. The parameters DAMPING and FPML have to be adapted to your problem. A good starting point is to set DAMPING to the average P or S-wave velocity of the medium and FPML to the dominant frequency of the source wavelet. In some cases the PMLs can become unstable, so you have to tweak the DAMPING and FPML parameters a little bit more.
Best regards,
Daniel

Dear Daniel,
Thank you for your kind response. I apologize for the delayed reply. I have read some papers about CPML. After following your advice and conducting further tests, I realized that I had set the wrong DAMPING values. I have now resolved this issue.
Once again, I appreciate your assistance and wish you all the best.
Sincerely,
Zhang Shuo
