Item Open Access Retrieval of effective parameters for bianisotropic metamaterials with omega shaped metallic inclusions(Elsevier, 2011-11-18) Li, Z.; Aydin, K.; Özbay, EkmelBianisotropic metamaterials including Ω-shaped metallic elements are investigated experimentally and theoretically. 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.Item Open Access Transmission properties of composite metamaterials in free space(American Institute of Physics, 2002) Bayındır, Mehmet; Aydin, K.; Özbay, Ekmel; Markoš, P.; Soukoulis, C. M.We propose and demonstrate a type of composite metamaterial which is constructed by combining thin copper wires and split ring resonators (SRRs) on the same board. The transmission measurements performed in free space exhibit a passband within the stop bands of SRRs and thin wire structures. The experimental results are in good agreement with the predictions of the transfer matrix method simulations. © 2002 American Institute of Physics.
