利用小型化频率选择表面实现宽带电磁透明

为了实现微波宽带高透明性材料,采用了小型化频率选择表面的方法,设计了一种由一层容性贴片和一层S形感性网栅构成的电磁透明材料,结果表明,这种电磁透明材料-1 dB相对带宽可达99.4%,实验结果与仿真结果吻合。同时,斜入射实验结果显示,该结构在横电波和横磁波偏振入射波40°角入射条件下仍具有较好的角度稳定性。

Using Miniaturized Frequency Selective Surface to Realize Broadband Electromagnetic Transparency

In order to achieve microwave broadband and high transparency materials, we have adopted a method of miniaturizing the frequency selection surface. An electromagnetically transparent material consisting of a layer of capacitive patch and a layer of S shaped inductive grid is designed. The results show that the -1 dB relative bandwidth of this electromagnetically transparent material can reach 99.4% and the experimental results are in good agreement with the simulation results. At the same time, the oblique incidence experiment results show that the structure still has good angular stability under the incident condition of the transverse electric wave and the transverse magnetic wave with a polarized incident wave angle of 40°.
