我们从实验和数值上证明了基于双层交叉线的超材料具有巨大的旋光性、圆二色性和负折射率。所提出的手性设计提供了一种更简单的几何结构和更有效的方式来实现在任何频率的负折射率。我们还开发了一个手性材料的检索程序，成功地适用于圆偏振波。
We demonstrate experimentally and numerically that metamaterials based on bilayer cross wires give giant optical activity, circular dichroism, and negative refractive index. The presented chiral design offers a much simpler geometry and more efficient way to realize negative refractive index at any frequency. We also developed a retrieval procedure for chiral materials which works successfully for circularly polarized waves.
