摘要：

We present the experimental realization of a one-dimensional left-handed/right-handed resonator. The left-handed (LH) part of the resonator is formed by a solid-state-like metamaterial composed of Omega metallic structures, while the right-handed part is just air. The resonant behavior is successfully observed and an acceptable Q value is obtained. Through phase measurement, we verify that the LH metamaterial layer acts as a phase compensator. Further proof is given by varying the thicknesses of both layers simultaneously to achieve the same resonant frequency under the limitation of total phase difference less than 2 pi, which is a criterion dramatically different from traditional cavity resonators.
