In this Letter, we report two kinds of metamaterial modulators based on hollow complementary omega-ring-shaped (HCΩ) structures, which are fabricated on parylene-C thin film with high flexibility and can realize dual-band amplitude tunability. The first type of structure (HCΩ-I) consists of identical unit cells along a similar direction, achieving different tunability under different compression directions but suffering from polarization dependence. To investigate the effect of unit cell direction on polarization direction, the unit cells in the HCΩ-I device are rotated by 90° in sequence to form a symmetrical type of structure (HCΩ-II), which successfully produces reverse dual-band variation of transmission with good polarization independence. These two developed flexible modulators with varied tunable ability will have a promising application in terahertz detection, sensing, and imaging.

具有双频可调谐性的空心互补Ω环形超材料调制器

在这封信中,我们报告了两种基于空心互补Ω环形(HCΩ)结构的超材料调制器,它们是在聚对二甲苯-C薄膜上制造的,具有很高的柔韧性,并且可以实现双频带幅度可调性。第一种结构(HCΩ-I)由沿相似方向的相同单位晶胞组成,在不同的压缩方向上实现了不同的可调谐性,但存在偏振依赖性。为了研究晶胞方向对极化方向的影响,将HCΩ-I器件中的晶胞依次旋转90°,以形成对称类型的结构(HCΩ-II),该结构成功地产生了反向的双频带变化。传输具有良好的极化独立性。
