A planar composite metamaterial consisting of bilayers of metal cutwire pairs and long wire pairs which are separated by a thin dielectric layer is designed and fabricated for microwave frequencies. The simulated and experimentally measured transmission spectra of the metamaterial and its individual components (cutwire‐only and wire‐only) indicates that the metamaterial exhibits a transmission band within the common stop bands of its components, and thus acts as a medium with negative index of refraction. The existence of n < 0 is further supported by a refraction experiment. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
