Hello,
I am modifying a 2D time-domain PML code (see attached by Joachim) to incorporate the existence of evanescent waves.
In some other problems, there exist evanescent waves. In this case I want to set the pml scaling parameter has a negative imaginary part to accelerate the decay of evanescent waves. Does the pml support this feature?
Best,
Shixu
