Experimental realization of a one-dimensional LHM-RHM resonator

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 Ω 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 2π, which is a criterion dramatically different from traditional cavity resonators.
