Hey everybody...

i´m searching for some information about the epsilon of some metals like copper, gold, aluminium, silver and lead. The frequency range should be between 300 MHz and 1 GHz.

Any experiences or knowledge you can share?

Thanks a lot and best regards,

Caspar

Hi Caspar,
The dielectric permittivity of metals is infinite, (at least if you consider a perfect conductor, but for all practical purposes metals sort of are),
that's the reason why you can't tell gold apart from iron.
Regards,
