Frequency dependent properties

Hey all,
I am working on trying to discriminate various materials based on their response to fringing electric fields. The problem is that it seems COMSOL only allows for 1 value for relative permeability/permittivity. Is it possible to define these as a function, rather than just a single value? I realize that often there aren't significant differences, but we are trying several techniques that are useless unless the material will respond differently to different frequencies.
anybody got anything on this?
Thanks in advance!

Hi
normally in COMSOL any entry can be a function or a piecwise table lookup

Good luck
