Abstract :
In this paper the problem of metamaterial constitutive parameters extraction is considered. The leading methods reviewed are: the S-parameters method, the field averaging method and the eigen-solution method. A new approach based on modal analysis using plane wave expansion of Bloch functions is proposed. The existing methods are reviewed and compared in performance to the proposed method.
