摘要
将两种雷达吸波材料(RAM)按照1∶1的体积比设计成不同的周期结构,利用电磁场有限元软件对反射率进行计算。计算结果表明,周期结构吸波材料的吸收峰位于两种吸波材料之间,周期结构的大小、形状以及吸波材料在周期结构中的位置对吸波性能均有较大影响。
The different periodical structures were designed using two different radar absorbing materials whose volume ratio was 1∶1,and their reflectivities were calculated by the finite element software.The calculation results show that the absorbing peaks of the periodical structures locate between those of the two original absorbing materials,and the sizes and patterns of the periodical structures,as well as the position of the radar absorbing materials,all have influences on the radar absorbing properties to som...
