在这项研究中，提出并展示了一种新的可调超颖表面（MS）的设计。MS可以实现多种功能，例如辐射和散射操纵。为了设计MS单元，使用四个变容二极管，以便可以通过调节二极管偏置电压来调谐谐振和同相反射频带。对于整个MS阵列，添加馈电结构以实现辐射性能。同时，通过调整不同单元的反射相位，可以实现低散射性能。实测结果与仿真结果吻合良好，验证了所提出设计的有效性。这项工作为我们设计多功能可调MS和其他相关的实际应用提供了一种有效的策略。
In this study, a novel design of tunable metasurface (MS) is proposed and demonstrated. The MS can realise multiple functions, such as radiation and scattering manipulation. To design MS unit, four varactor diodes are used so that resonant and in‐phase reflection band can be tuned through adjusting diode bias voltage. For the whole MS array, feeding structures are added to realise radiation performance. Meanwhile, adjusting reflection phase of different units can achieve low scattering performance. Measured results agree well with simulations, verifying the validity of the proposed design. This work offers us an effective strategy to design multi‐functional tunable MS and other related practical applications.
