| 摘 要： | 提出了一种具有独立调控透射幅值与相位能力的新型惠更斯单元结构,能够实现透射幅值在0~0.9、透射相位在0~2π的任意调控。基于广义斯涅耳定理对惠更斯单元进行排列,设计并制备出具有异常透射功能的超表面结构。全波仿真结果表明超表面能够使频率为10 GHz的正入射电磁波产生约60°的偏折。近场测试结果与仿真结果基本一致,进一步证实了超表面结构设计的正确性。

| Abstract: | A novel Huygens particle,of which transmission magnitudes and phases can be controlled independently,is proposed here.The transmission magnitude can be arbitrarily tuned from 0 to 0.9,while the transmission phase is between 0 and 2π.Aligning Huygens particles based on generalized snell’s law,a metasurface structure with function of anomalous transmission is designed and fabricated.Full-wave simulation results prove that the plane electromagnetic wave normally incident from the bottom is nearly steered to 60°by the designed Huygens metasurface at 10 GHz.The near-field measurement results are basically consistent with the simulations,which demonstrates the correctness of desinged metasurface further. |
