Design of an ultra-wideband thin frequency selective surface absorber

  • 摘要: 设计了一种新型集总电阻加载超宽带薄型频率选择表面(FSS)吸波体。该吸波体使用单层单谐振FSS损耗层结构,具有厚度薄、宽带吸波且极化稳定的特点。FSS损耗层单元结构采用非单元中心对称轴集总电阻加载方法,并结合非均匀金属导带宽度和圆顶枝节加载设计有效拓宽了吸波带宽。该吸波体的等效电路分析及全波仿真结果均表明该结构在6.0~26.77 GHz频段内对电磁波吸波率能够达到90%,相对带宽达到126.8%。该吸波体总厚度为0.086λLλL为吸波频段最低频率对应波长),仅为Rozanov理论极限厚度的1.09倍。对该吸波体进行加工与测试,实测结果与仿真结果一致,验证了设计的有效性。
