Relative permittivity/permeability for metamaterial

  1. Feb 23, 2015 #1
    Hi Guys,

    Don't know if I posted at the right place...
    can anyone tell me how to calculate the relative permittivity/permeability of a 3D microwave metamaterial for Q-band (wavelength ranging from 6mm to 9mm)?

    From refractive index and impedance at certain frequency.
    For example, This paper deals with THz range, but described principles hold in general
