We present an overview of unique properties of metamaterials, especially negative index materials. These have allowed novel applications, concepts and devices to be developed in the past decade. A review of the progress made in this field is presented with a focus on microwave devices and applications in wireless communications. Since a metamaterial can be regarded as a continuous medium with effective dielectric permittivity and effective magnetic permeability, we present the procedure for the extraction of effective electromagnetic parameters for a guided wave structure with split-ring resonators. As examples, our own designs of bandpass and triple-band filters, which are constructed using metamaterial-inspired resonator elements, are presented and discussed. |
