一维超材料是利用三个相连的欧米茄环背靠背印刷，并在电介质衬底的两侧反转。透射实验和棱镜实验均得到了左旋频带存在的一致结果。实验表明，该方法减小了损耗，扩大了左频带。(C) 2004年美国物理研究所。
A one-dimensional metamaterial is realized using three connected Omega rings printed back-to-back and reversed on two sides of a dielectric substrate. Both transmission and prism experiments are reported, yielding concordant results of the presence of a left-handed frequency band. Experiments show reduced losses and an enlarged left-handed frequency band. (C) 2004 American Institute of Physics.
