Abstract

Metamaterial (MTM) is an artificial composite material for which we can change its electromagnetic properties [1]. The equivalent circuit approach of MTM was developed by Caloz and Itoh [2] and Sanada et al. [3], and this approach has led to the concept of composite right- and left-handed (CRLH) materials. This concept fully takes into account the parasitic right-handed (RH) effects, which is unavoidable in a practical application. The zeroth-order resonator (ZOR) has the mode number zero, and its resonator length is invariant of its wavelength. Sanada et al. [3] first proposed MTM-ZOR and realized it in microstrip configuration. Using the MTM-ZOR technique, several researchers [4]-[8] have designed band pass filters (BPFs) in different frequency bands.
