电磁波的极化在光电子学、生命科学显微镜和照相显示等领域的应用中起着至关重要的作用[1]。在天然材料中,一个极化方向的电磁波向其垂直方向的转换通常很弱。本文提出了一种可调谐的超材料,它在太赫兹波段将极化方向旋转到20°。这种超材料可以变换成其不可叠加的镜像,并可调谐偏振角,可用于太赫兹波段的可调谐波片和光开关。
The polarization of electromagnetic (EM) wave plays an essential role in the application of optoelectronics, life science microscopy and photographic display[1]. The conversion of EM wave in one polarized direction to its orthogonal direction is usually quite weak in natural materials. This paper presents a tunable metamaterial which rotates the polarized direction up to 20° in THz regime. The metamaterial can be transformed to its non-superimposable mirror image and tunes the polarization angle, which can be applied as tunable wave plate and optical switch in THz regime.
