实验研究了有耗单负(SNG)超材料中波的传输特性。研究了有耗负电子(ENG)单分子膜和由有耗负ENG材料和负MNG(MNG)组成的SNG双层膜的模型结构。仿真和实验结果表明,通过增加损耗系数和增加有损SNG的厚度两种途径可以提高有损SNG材料的透过率。这种有损耗的ENG材料是通过使用嫁接有辐射单元的复合右手和左手传输线来物理制造的。实验结果与理论分析吻合较好。
The properties of the wave transmission in the lossy single-negative (SNG) metamaterials are experimentally investigated. The model structure of lossy epsilon-negative (ENG) monolayer and SNG bilayer consisting of a lossy ENG material and a mu-negative (MNG) are considered in this work. Simulation and experimental results show that the transmittance of the lossy SNG materials can be enhanced by two approaches, increasing dissipation coefficient and increasing the thickness of the lossy SNG. The lossy ENG material is physically fabricated by using composite right- and left-handed transmission lines grafted with radiation unit cell. The experimental results are in very good agreement with the previous theoretical analysis.
