What's simpler Berenger PML or Gedney UPML?

hi everyone

I want to know which one is more common used in EM simulation toward Berenger PML and Gedney PML(UPML)?Which one is more simple?Thanks!!!

Try UPML

oh,thank you Fuga.Why choose it, I want to know.

There is no different of absorbing effects between UPML and PML.
But UPML is easy to understand and implement.

Does someone know CPML??

which one is better??

Hi,
How can one implement 3D FDTD UPML using C++.
I need it for my dissertation.

Dear all
pml ,upml and cpml all of them absorbing boundry condition u can implement any of them and the eror will not be large but each of them tequneques used in absorbing so if u want any code for matlab in cpml u can find it in dr atef elsherbin book that book will help u very much about cpml.
