摘要
本文提出并论证了一种基于几何相位的具有高效透射窗的漫射散射超表面。该超表面的元原子由散射抵消层、介电间隔层和带通频率选择表面(FSS)层组成。超材料的二元元是元原子，它的副本以90°倾斜角度旋转。全波电磁仿真结果表明，10 dB RCS减带范围为6.4 GHz ~ 11.3 GHz，传输频段为15.1 GHz，插入损耗为0.3 dB。制作了该材料的样品并进行了测量，以验证仿真结果。
Geometric Phase Based Diffuse Scattering Metasurface with High-efficient Transmission Window
In this paper, a geometric phase based diffuse scattering metasurface with a high-efficient transmission window is proposed and demonstrated. Meta-atom of this metasurface consists of scattering cancellation layer, dielectric spacer layer and band-pass frequency selective surface (FSS) layer. The binary elements of the metamaterial are meta-atom and its copy rotated by 90° inclined angle. Full-wave electromagnetic simulation indicated that 10 dB RCS reduction band is from 6.4 GHz to 11.3 GHz while the transmission band is 15.1 GHz with 0.3 dB insertion loss. Sample of this metamaterial was fabricated and measured to validate the simulation results.
