我们展示了一种基于间隔导电非磁性开口环谐振器和连续导线的周期性阵列的复合介质，该介质在微波范围内表现出有效导磁率μ（eff）（欧米茄）和介电常数epsilon（eff）同时为负值的频率区域。（欧米茄）该结构形成了“左手”介质，据预测，这种介质会出现多普勒效应、切伦科夫辐射，甚至斯内尔定律都被颠倒了。现在可以通过微波实验来测试使用这种新的超材料的这些影响。
We demonstrate a composite medium, based on a periodic array of interspared conducting nonmagnetic split ring resonators and continuous wires, that exhibits a frequency region in the microwave regime with simultaneously negative values of effective permeability mu(eff) (omega) and permittivity epsilon(eff)(omega) This structure forms a "left-handed" medium, for which it has been predicted that such phenomena as the Doppler effect, Cherenkov radiation, and even Snell's law art inverted. It is now possible through microwave experiments to test for these effects using this new metamaterial.
