PML Questions

Hello,

I think I’ve encountered a problem in my use of PML, and I am unsure of how to fix it. I am trying to calculate the cross section extinction of a gold nanoparticle in water. I find that the final extinction calculation is same regardless of whether PML is present. Am I using the PML commands incorrectly?

Thanks
