# Relative permittivity of gold at radio-frequencies

What is the relative permittivity of gold at radio-frequencies or specifically around 15-20MHz?

Model it as a PEC, if you really want to be specific though, wikipedia gives the conductivity as being 45.2 mega-mhos. The conductivity and permittivity will probably not change until you get into the terahertz range. Then, some metals, like silver I know, will behave as a plasma.
