Abstract

|A Metamaterial Terahertz perfect absorber is proposed in this letter. The structure comprises Vanadium oxide (VO 2 ) resonator hexagonal rings placed on top of a silicon dioxide (SiO 2 ) substrate in a concentric pattern on a metal ground layer, with 1 THz and 6 THz operating frequency. Numerical studies are done by an electromagnetic solver. The results show almost perfect absorption, with 112% average absorption at diﬀerent incident polarization angles, in the range of 1.64 to 6.1 THz. The optimization is carried out on physical dimensions for maximum absorption results. The proposed design can be used as a highly eﬃcient absorber in applications like solar energy harvesting, cloaking, sensing, imaging technology, and EMC projects.

超材料完美吸收剂采用氧化钒六方环结构

本文提出了一种超材料太赫兹完美吸收体。该结构包括氧化钒(VO 2)谐振器六角形环，以金属接地层上的同心图案放置在二氧化硅(sio2)衬底上，工作频率分别为1太赫兹和6太赫兹。数值研究是由电磁求解器完成的。结果表明，在1.64 ~ 6.1 THz范围内，不同入射偏振角下的平均吸收率为112%，几乎完全吸收。为了获得最大的吸收效果，对物理尺寸进行了优化。所提出的设计可以用作太阳能收集、隐身、传感、成像技术和EMC项目等应用中的高效吸收器。
