摘　　要：为保证伪装伪装效果的前提下进一步提升其雷达隐身特性,设计了一种基于方环结构的柔性透明编码超表面。通过改变其表面相位梯度编码方式,将电磁波散射到异常角度,有效降低了其后向散射。仿真和实验结果表明,两种编码模式均能实现X波段范围衰减10dB的目标,二维梯度编码表面相较一维梯度编码的衰减频宽略大。与其他柔性编码超表面相比,该方法表面设计结构简单,厚度较薄,仅为3mm左右,有望实现微波隐身和光学伪装的完美结合。In order to further improve the radar stealth characteristics while ensuring the camouflage effect of equipment,a flexible transparent coding meta-surface based on square ring structure was designed.By changing the coding method of the surface phase gradient,the electromagnetic wave is scattered to the abnormal Angle,and the backscattering is effectively reduced.Simulation and experimental results show that both coding modes can achieve the target of 10dB attenuation in X-band range,and the attenuation bandwidth of two-dimensional gradient coding surface is slightly larger than that of one-dimensional gradient coding surface.Compared with other flexible coding meta-surfaces,the proposed method has simple surface design structure and thin thickness,only about 3mm,which is expected to achieve the perfect combination of microwave stealth and optical camouflage.
