摘要

共用孔径双波段透反射元表面可同时在两个独立频段上对电磁波的传输和反射进行独立操控。然而,当子元件集成在一个紧凑的区域内时,尺寸限制和意外耦合限制了可实现的带宽和相位覆盖范围。本研究提出了一种基于物理学的策略,用于定制元表面元件的谐振场和电流分布,从而有效抑制元件间的耦合,并扩大相位范围,即使在有限的几何尺寸内也是如此。利用这种方法,设计出了具有宽带操作和 2 位相位离散化的共享孔径双波段跨反射元表面。元原子设计策略的功效通过一个 $40/times 40$ 组件原型得到了证明,该原型可在 14.5-20.7 GHz 的传输频率和 30-40 GHz 的反射频率下独立产生扭曲轨道角动量(OAM)涡流束。该设计策略为开发双波段、宽波段跨反射元原子提供了一种新方法,有望应用于多功能波前整形。

Broadband Transreflective Metasurface for Multifunctional Dual-Band OAM Engineering
Shared-aperture dual-band transreflective metasurfaces enable independent manipulation of electromagnetic waves in both transmission and reflection across two separate frequency bands simultaneously. Nevertheless, dimensional constraints and unintended coupling limit the achievable bandwidth and phase coverage when the subcomponents are integrated in a compact area. This study presents a physics-based strategy to customize the resonant field and current distributions for the metasurface components, effectively suppressing inter-component coupling and expanding the phase range even within confined geometries. Using this proposed method, a shared-aperture dual-band transreflective metasurface with wideband operation and 2-bit phase discretization is designed. The efficacy of the meta-atom design strategy is demonstrated by a $40\times 40$ component prototype, which independently generates twisted orbital angular momentum (OAM) vortex beams in transmission at 14.5–20.7 GHz and in reflection at 30–40 GHz. The design strategy offers a novel approach for developing dual-band, wideband trans-reflection meta-atoms with potential applications in multifunctional wavefront shaping.
