通过自组装方法设计并在实验和模拟中演示了米氏共振太赫兹吸收器。单层二氧化锆（ZrO2）微球固定在具有设计网格的铜膜上，通过由聚二甲基硅氧烷（PDMS）组成的复合墨水系统直接书写制造。更重要的是，经济高效地创建了不同的间距和阵列配置，展示了视觉性能。磁共振导致样品在约 0.4 THz 处产生接近一致的吸收。这项工作展示了高效的太赫兹吸收器，并强调了一种新颖的直写制造方法，该方法可以扩展到生产其他应用光学器件。 (C) 2018 年美国光学协会根据 OSA 开放获取出版协议条款
Mie-resonance terahertz absorbers by self-assembly method are designed and demonstrated in experiments and simulations. A monolayer of zirconium dioxide (ZrO2) microspheres fixed on a copper film with designed grids that were manufactured by direct writing with a composite ink system composed of polydimethylsiloxane (PDMS). More importantly, different spacing and array configurations were created economically and efficiently, showing visual performance. Magnetic resonance leads to near-unity absorption at about 0.4 THz in the samples. This work demonstrates efficient terahertz absorbers and highlights a novel direct writing fabrication method that can be extended to produce other optical devices for applications.
