摘要

电磁波的极化在光电子学、生命科学显微镜和摄影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，电磁波在一个极化方向向正交方向的转换通常很弱。本文提出了一种可调谐超材料，该材料在太赫兹区极化方向可旋转达20°。该超材料可变换成非重叠镜像，并可调节偏振角，可作为太赫兹波段的可调谐波片和光开关。

Thz polarizer using tunable metamaterials

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.
