  • 本文针对一种波导谐振腔集成馈电型惠更斯超表面重点进行了波束调控方法研究. 通过合理地调节单元中电偶极子和磁偶极子的尺寸参数, 对惠更斯超表面单元的相位调控范围实现了接近360°的相位覆盖, 并且保持了较高的传输效率. 研究中通过分析开口波导谐振腔馈电模式的谐振机理, 构建了具备集成馈电功能的开口波导谐振腔结构, 并表征了其电场极化特性, 掌握了口面电场分布规律. 在此基础上, 根据广义菲涅尔定律构建出具有不同相位梯度的惠更斯超表面单元阵列, 将其嵌入开口谐振腔, 从而保障波导内的电磁波定向辐射是采用一维惠更斯超表面机制工作. 仿真和实验结果均证明了所提出的波导谐振腔集成馈电超表面能有效地实现对辐射波方向的高效调控. 这种波导谐振腔加载超表面的方式不但能够实现对电磁波辐射角度的灵活调控, 提高电磁波调控的效率, 而且所设计的超表面具有结构紧凑的优点, 有利于系统的集成和小型化设计.
    In this paper, cavity-excited Huygens’ metasurface is proposed for high-efficiency wavefront manipulation. By adjusting the length of electric dipole and magnetic dipole , the proposed Huygens’ metasurface meta unit can provide nearly 360° phase coverage with sufficiently high transmission efficiency. Based on the analysis of the resonance mode of the cavity, the Huygens’ metasurface has successfully performed its function by adopting integrated feeding method. According to the generalized Snell’s law, metasurfaces with different phase gradients are designed. Combined with the cavity structure, one-dimensional Huygens’ metasurfaces excited by cavity is realized, which can directionally emit the electromagnetic waves from the cavity. Both the simulation and experimental results show that the proposed cavity excited metasurfaces can effectively manipulate the direction of the emitted beam. Such a kind of cavity-excited metasurface can flexibly control the emission angle of the electromagnetic wave, reduce the energy loss and improve the efficiency of the electromagnetic wave. These designs have the advantages of compact, light and easy integration.
