pml infinite site:edaboard.com

Hello,
I am working with FDTD and I have already written some codes, but I found out that inorder to simulate an infinite space, i need to use an ABC. My supervisor told me to use PML.The problem is that I don't know how to code the PML into my program. Please, if anyone have a PML code in C++/C, it will be of great help to me. Alternatively, if anyone can explain the process, that will also help.
Thanks
