one question about 2-D UPML matlab code
I wrote a 2-D UPML matlab code but I have a problem. When the few waves reflect from corner there is not symetric despite of, all of things in my code is symetric.
thanks for your help.
Hi
The problem may be due to error in the implementation of the corner region. Since two PML layers overlap in the corner region, it has to be treated carefully.
There is a chance that you might have updated the same filed component (e.g., Ex, Ey , Hz) twice in the corner region. You might have updated it during the implementation of bottom/top boundary as well as left/right boundary. This will create instability in the corner regions.

Hi
I can upload a 3D UPML code (This comes along with the Taflove-Hagness book, Third Edition 2005), if you need it.
