标题： Experimental demonstration of terahertz metamaterial absorbers with a broad and flat high absorption band

摘要： 我们介绍了太赫兹超材料吸收器的设计、数值模拟和实验测量，该吸收器在宽入射角范围内对横向电极化和横向磁极化都具有宽而平坦的吸收顶。 超材料吸收器单元结构包含两组在不同但接近频率下谐振的结构。 整体吸收光谱是各个组件的叠加，在较大的带宽内顶部变得平坦。 实验结果与数值模拟结果高度一致。 显示英文摘要

摘要： We present the design, numerical simulations and experimental measurements of THz metamaterial absorbers with a broad and flat absorption top both for transverse electric and transverse magnetic polarizations over a wide incidence angle range. The metamaterial absorber unit cell consists of two sets of structures resonating at different but close frequencies. The overall absorption spectrum is the superposition of individual components and becomes flat at the top over a significant bandwidth. The experimental results are in excellent agreement with numerical simulations.
