A passband is observed for a composite metamaterial (CMM) based on an Ω-medium below the plasmonic frequency of the corresponding closed CMM. The effective parameters (refractive index, impedances, permittivity, permeability, and magnetoelectric coupling coefficient) are retrieved for the Ω-medium and the CMM based on it. Our retrieval results show that the passband observed for the CMM is a band with positive refractive indices. Our retrieval results confirm the deductions of our previous reports.EnglishBianisotropyEffective parametersMetamaterialsOmega mediaBianisotropic metamaterialsBianisotropyComposite metamaterialsEffective parametersMagnetoelectric couplingsMetallic elementsMetallic inclusionsOmega mediaPass bandsPlasmonicMetallic compoundsRefractive indexMetamaterialsArticle10.1016/j.photonics.2011.11.002
