Can I simulate thin metal film's optical effects in ewfd module?

Hi All,
I want to simulate the reflectance and transmittance spectra when a light incident on a thin metal film (100nm) on a sapphire.
I looked through the application on COMSOL website: Anti-Reflective Coating with Multiple Layers. The physics they were used is gop, and the thin layer specified by a attribute called "thin dielectric film". However, I want to model a thin metal which is not a dielectric material.
So I tried ewfd module by creating a thin layer in geometry and put in metal material.
Since there is no attribute called "thin metal/dielectric film" in ewfd, can I use this module to simulate thin film effect?
Thanks,
;)

Hello,
With regards to modeling thin films of metal in electromagnetics, you may want to look to the Transition boundary condition.
See this example:

As an alternative to the above, you may also find this interesting:
