Dielectric Constant and tanδ of Gold and Copper

Hello to everyone,

i am using IE3D to simulate an antenna. I will use for conductor Gold or Copper.

I am searching about relative constant and Loss tangent δ. Ιs anyone knows

these value in Microwave Band? Also, in optical frequencies is there any significant

deviation ?

For conductors you are usually using the resistance or the conductance instead of the dielectric constant and the tangent δ.
These values can be found on the internet.
Furthermore, the simulator should have a material database.

Thanks very much for your reply !!!
