我们提出了一个一维左手/右手谐振腔的实验实现。谐振器的左手（LH）部分由/spl Omega/金属结构组成的固态超材料形成，而右手部分只是空气。成功地观察到了谐振行为，并获得了可接受的Q值。通过相位测量，我们验证了LH超材料层作为相位补偿器。通过同时改变两层的厚度以在总相位差小于2/spl π/的限制下实现相同的谐振频率给出了进一步的证明，这是与传统的腔谐振器显著不同的标准。
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 /spl 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/spl pi/, which is a criterion dramatically different from traditional cavity resonators.
