| 摘 要： | 提出了一种空气／左手介质／右手介质／金属的双层吸波体结构，引入左手材料做匹配层，利用传输线模型与计算机仿真方法考察了左手材料各个参数变化对吸波性能的影响．仿真结果表明：左手材料各个参数适当的选择对提高吸收率起着重要作用；在给定参量条件下，左手材料层厚度最佳值为1mm；随着左手材料层厚度的变化，吸波体的吸收峰值将降低且峰值对应的频率也将分别向低频或高频移动．

| Abstract: | A double-layer wave-absorbing structure made up of air/left-handed-material/right-handed-material/metal is proposed,in which the left-handed material is used as a matching layer.The effects of variations in the parameters of the left-handed material on the structure's wave-absorption property were investigated,then digitally simulated using a transmission line model.The results show that the choice of parameters plays an important role in improving the absorption rate.Given the electromagnetic parameters used in this paper,it is found that the optimal thickness of the LHM layer is 1mm.As thickness varies,the peak value of the absorption curve declines and the corresponding frequency becomes lower or higher. |
