摘要
本文提出了一种设计双频隐身超表面的方法,基于漫反射和吸波复合机理设计实现双频和超宽带的RCS减缩。首先设计几何相位单元和吸波体单元,随后采用伪随机数生成的办法确定了随机相位布阵,仿真结果表明该隐身超表面分别在4.06-4.2 GHz和7.6-21.2 GHz两个频段内实现了6d B的RCS减缩,加载吸波体不会影响漫反射减缩性能,该隐身超表面还具有极化不敏感性。为设计双多频隐身器件开辟了一种新的思路。
A novel approach for design dual-band low-scattering metasurface is proposed in this paper. The dual-band and ultra-wideband RCS reduction can be realized based on combination of diffusion and absorber. Firstly, the geometrical phase unit cell and absorber unit cell are designed.Then, the random phase configuration was realized by generation of pseudo-random number. The simulation results show that this metasurface can suppress backscatter RCS more than 6d B over 4.06-4.2 GHz and 7.6-21.2 GHz. In addition, the diffusion performance still kept after loading absorber, and the metasurface has the advantage of polarization-insensitive. This paper open up a new route to design the dual-band or multi-band stealth devices.
