作者展示了一种手性光子超材料，其手性由相互扭曲的不连接层之间的电磁耦合提供。在可见光和近红外光谱范围内，该材料表现出高达2500度/mm的偏振旋光功率，并显示出相对较低的损耗和可忽略的圆二色性，使其成为开发手性负折射率介质的有希望的候选者。(C)2007年，美国物理学会。
The authors demonstrate a chiral photonic metamaterial with chirality provided by electromagnetic coupling between mutually twisted unconnected layers. In the visible and near-IR spectral ranges, the material exhibits polarization rotatory power of up to 2500 degrees/mm and shows relatively low losses and negligible circular dichroism, making it a promising candidate for the development of chiral negative index media.
