摘　　要：本文介绍了一种通过电阻加载与介质支节加载的宽带新型人工电磁材料吸波器。通过对等效电路的研究,分析出了实现宽带吸波器的方法及影响吸波性能及吸波带宽的重要参数,并在新型电磁人工材料研究的基础上,提出了由电阻连接两个开口谐振环的单元结构,将这些单元结构周期排列,并加以介质支节和金属短路板实现了宽带新型人工电磁材料吸波器。通过仿真软件分析和对比了影响该宽带结构吸波性能的重要参数,最后将最优参数加工测试。测试结果显示,此宽带吸波器在8.1GHz-11.9GHz频带内的S11在-10d B以下。In this paper a novel aritificial electromagnetic material-based wideband absorber is presented. It is composed of a periodic array of double SRR resonators loaded with lumped resistor, a dielectric substrate,and a metal plate. Baded the analysis of equivalent circuit, the relative method of realizing a wideband absorber and the main influence factors of its characteristcs are presented and then the detailed structure are proposed where one lumped resistor is placed between each two split ring resonator cells. We simulated, fabricated, measured, and analyzed this absorber.The experimental results show that the feflectance (S11) is below-10 dB at normal incidence in the frequency range of 8.1 GHz-11.9 GHz.
