报道了第一种利用微加工技术制备的电磁超材料（EM 3）。它们是基于Pendry等人提出的杆裂环谐振器设计[IEEE Trans. Microwave Theory Tech. 47，2075（1999）]并由Smith等人[Phys.Rev.Lett. 84，4184（2000）]中所描述的。数值模拟和远红外（FIR）透射光谱的实验结果支持的结论，微加工复合材料是EM 3在1-2.7太赫兹范围内。这将EM 3可用的频率范围扩展了约3个数量级，从而为验证电磁理论上不寻常的物理含义以及构建新型电磁和光学设备提供了广泛的机会。
The first electromagnetic metamaterials (EM3) produced by microfabrication are reported. They are based on the rod-split-ring-resonator design as proposed by Pendry et al. [IEEE Trans. Microwave Theory Tech. 47, 2075 (1999)] and experimentally confirmed by Smith et al. [Phys. Rev. Lett. 84, 4184 (2000)] in the GHz frequency range. Numerical simulation and experimental results from far infrared (FIR) transmission spectroscopy support the conclusion that the microfabricated composite material is EM3 in the range 1-2.7 THz. This extends the frequency range in which EM3 are available by about 3 orders of magnitude well into the FIR, thereby widely opening up opportunities to verify the unusual physical implications on electromagnetic theory as well as to build novel electromagnetic and optical devices.
