Résumé : 

In this study, an extraction procedure using a ground coplanar wave guide GCPWG structure [1] is proposed to obtain the complex permittivity and permeability of unknown thins film materials. The method is validated for unknown materials that having the following properties: dielectric material losses, dielectric material with losses, and magneto-dielectric material with loss, deposited on a substrate with known dielectric properties. Full wave electromagnetic simulations are used to obtain the S parameters of the structure as a function of frequency [2], which are used with conformal mapping technique CMT [3] to calculate the complex permittivity and permittivity of the unknown materials. Results shown that, the parameters of the material extracted are accurate with an error of 5% for the real and imaginary values, in comparison with the values specified on [1GHz 3 GHz]. This proposed method, will prove to be useful for measuring the complex permittivity and permeability of thin films for a wide range of applications.
