三维(3D)和二维手性超材料(CMM)分别表现出圆二向色性和圆转换二色性。层层手性超材料作为三维坐标测量机的一种，有望表现出与块状三维结构(如螺旋)相同的性质。然而，在本文中，我们用理论和实验的方法证明了逐层坐标测量机同时表现出圆二向色性和圆转换二色性。这项工作表明，在层层坐标测量机中也可以观察到圆偏振的非对称传输。此外，我们还为层次式坐标测量机中非对称传输的存在提供了一些必要的条件。(C)2013年美国光学学会
The three-dimensional (3D) and two-dimensional (2D) chiral metamaterials (CMMs) have been proved to exhibit circular dichroism and circular conversion dichroism, respectively. The layer-by-layer chiral metamaterials, as a category of 3D CMMs, are expected to show the same properties as bulk 3D structures (e. g. helices). However, in this paper, we demonstrated that the layer-by-layer CMMs exhibit circular dichroism and circular conversion dichroism simultaneously by using both theoretical and experimental methods. This work showed that asymmetric transmissions of circular polarizations can also be observed in layer-by-layer CMMs. Moreover, we provided some necessary requirements for the existing of asymmetric transmissions in layer-by-layer CMMs. (C) 2013 Optical Society of America
