标题： Fixed-Frequency Reconfigurable Leaky-Wave Antennas with Simplified Biasing

摘要： 这项工作介绍了一种可重构的漏波波导天线，采用简化的偏置方案，在固定频率下实现动态波束转向。 与之前利用可调超表面作为辐射孔径的超表面辅助漏波波导天线不同，我们的方法仅将它们用作波导壁，以控制导引模式。 因此，所提出的结构消除了早期设计中通常需要的局部偏置方案，显著简化了偏置过程。 通过使用被动的、角度无关的超表面实现辐射，允许从正前方进行波束转向。 通过全波仿真验证了所提出设计的可行性和有效性。 显示英文摘要

摘要： This work introduces a reconfigurable leaky-waveguide antenna with a simplified biasing scheme for dynamic beam steering at a fixed frequency. Unlike prior metasurface-aided leaky-waveguide antennas that employ tunable metasurfaces as radiative apertures, our approach utilizes them as a waveguide wall solely to control the guided mode. As a result, the proposed structure eliminates the need for local biasing schemes commonly required in earlier designs, significantly simplifying the biasing process. The radiation is achieved by employing passive, angle-independent metasurfaces that allow beam steering across broadside. The feasibility and effectiveness of the proposed design are validated through full-wave simulations.
