摘　　要：设计了一种圆孔阵列全介质超表面,能够使一定频率入射的电磁波,借助法诺共振抑制多极子散射,从而实现完全透射。针对聚四氟乙烯陶瓷复合基板上的圆孔阵列实验样品开展测试,结果显示:当超表面单元结构的周期、圆孔半径和厚度分别为30,8.5和1.3mm时,入射电磁波在8.48GHz处的透射率为93.89%。透射率的测试与仿真结果基本一致,透射峰出现较小偏移且有所下降,是由于实验样品的加工偏差以及样品材料对电磁波有一定的吸收所致。本文设计的全介质透明超表面结构简单,制作容易,性能可靠,具有良好的应用前景。In this paper,a circular hole array all-dielectric metasurface was designed,which could suppress multipole scattering due to Fano resonance and achieve complete transmission of the incident electromagnetic waves with certain frequency.The experimental results of the circular hole array on the polytetrafluoroethylene ceramic composite substrate show that when the period,circular hole radius and thickness of the metasurface cell structure are 30 mm,8.5 mm and 1.3 mm,respectively,the transmittance of the incident electromagnetic wave at 8.48 GHz is 93.89%,which is basically consistent with the simulation results.The small shift and decrease of the transmission peak are due to the processing deviation of the experimental sample and the absorption of the sample material to the electromagnetic wave.This all-dielectric transparent metasurface has simple structure,easy fabrication,reliable performance and good application prospects.
