【摘要】 讨论了一种新型雷达吸收材料（ＲＡＭ）—旋波媒质的吸收特性，分析由旋波媒质构成的Ｄａｌｌｅｎｂａｃｈ屏的散射特性。研究表明，由于旋波量的引入，ＲＡＭ涂层的吸收能力有明显改善，且扩大了涂层的吸收带宽，减小了涂层的厚度，增加了涂层设计的自由度。更多还原

【Abstract】 The absorption characteristics of a new type of radar absorbing material(RAM)-chiralmedium are discussed,and the scattering characteristics of Dallenbach screen formed by chiral medium are analyzed.The results show that the absorbability of RAM layer is improved because of the introduction of the chirality,the absorbing frepuency band is widened,the thickness of the layer can be decreased,and thefreedom of design is also increased.更多还原
