In this paper, the hyperbolic metamaterials (HMs) based on the one-dimensional (1D) plasma photonic crystals is proposed, whose dielectric constant and group index can be obtained through the effective medium theory. By adopting an improved Thue–Morse sequence structure and using the transfer matrix method, the tunable single-frequency reflection in absorption (SFRA) with angle stability is achieved. The effects of incident angle, filling rate, and plasma collision frequency on the refractive index of HM and the SFRA are also analyzed respectively. The simulated results show that the incident angle makes no difference in the frequency position of the SFRA. However, a larger filling rate means that SFRA will move quickly to the lower frequencies, and the greater plasma collision frequency indicates that SFRA will appear in the higher frequencies. The better performance of SFRA can be realized in the cases of a smaller filling rate, plasma collision frequency, and θ (less t...

基于双频超材料吸收的单频反射电磁波调制及其角度稳定性

本文提出了基于一维（1D）等离子体光子晶体的双曲超材料（HMs），其介电常数和基团指数可通过有效介质理论获得。通过采用改进的Thue-Morse序列结构并使用传递矩阵方法，可以获得具有角度稳定性的可调单频吸收反射（SFRA）。还分别分析了入射角，填充率和等离子体碰撞频率对HM和SFRA折射率的影响。仿真结果表明，入射角对SFRA的频率位置没有影响。但是，较大的填充率意味着SFRA将快速移至较低频率，而较大的血浆碰撞频率表明SFRA将出现在较高频率中。
