Negative permittivity methods

  1. Dec 13, 2008 #1
    could anyone offer a decent explanation of how a negative permittivity (dielectric constant) is obtained using the wire-mesh method.. i understand the process with plasmons and metals but this one seems a bit beyond me at the moment <<! any thoughts??:biggrin:

    Re: negative permittivity methods/metamaterials

    even any thoughts on metamaterials in general would be nice
