摘　　要：提出了一种工作于电磁波平行入射情况下的双波段连通矩形谐振环结构单元左手材料吸波器,充分利用电磁超材料的强谐振损耗性质,通过合理设计左手材料的电磁参数,并利用CST对其进行结构进行仿真优化,设计出具有较佳吸波效果的吸波器,使其中两个吸收峰位于以5.41 GHz、7.11 GHz频段,且吸收率高于同频段的传统碳膜材料吸波器。制备了双波段连通矩形谐振环结构单元左手材料吸波器,并测量其传输特性。实验结果表明,实验与仿真结果一致。该吸波器可作为微波电路的衰减器,取代传统吸波器结构。A dual band connected rectangular resonant ring structure is proposed,which is designed to work in the case of parallel incidence of electromagnetic wave.Making full use of the strong resonant loss properties of electromagnetic metamaterials,by designing the electromagnetic parameters of left-handed materials reasonably and using CST to optimize the structure,a wave absorver with better absorbing effect is designed to make the two absorption peaks located in the 5.41 GHz and 7.11 GHz frequency bands and the absorption rate is higher than that of the conventional carbon membrane absorber.A left-handed material absorber of dual band connected rectangular resonant ring structure is fabricated and its propagation characteristics are measured.The experimantal results show that the experiment agrees well with the simulation results.The absorber can be used as attenuator for microwave circuit to replace the structure of traditional absorber
