Hello
I am learn how to implement the Uniaxial perfectly matched layers in COMSOL.
I am trying to simualte the radiation of a elctric dipole near an metal slab(drude model). In the lossless case,I found that the Uniaxial PML does not work's very well in the region of ω>ωp. And at some frequency point, the radiated power is negative.While in the lossy case, it will be fine. In this process, I choice s = 1+σ/(jωε_0 ).I am very confused and don't know the reason. Is there anyone can give me some suggestions, it would be greatly appreciated.
Thank you very much
