I want to design a nano antenna in CST MWS at center frequency of 191 THz or 1500nm. I read that at optical frequencies metal behave like plasmons and the material properties are calculated via Drude Model. I wanted to ask following;

1) What is this Drude model?
2) How can I calculate the material (Au/Ag) properties with Drude model? Formulas??
3) Are there any constant values for Gold and Silver calculated via Dride Model? As I found different values in diff papers??? [a]
4) How are the plasmonic frequency and scattering frequencies calculated at THz range via Drude model?
5) What is epsilon infinity values in CST for working with Drude model??

Awaiting positive replies,
