摘要

提出了一种基于空时编码元表面的能量自动扫描系统。通过应用渐进式延时、时变相位调制，系统在角度和范围上产生非均匀的、随时间变化的电磁场分布。此外，还演示了利用MUSIC算法的单通道定位系统使用所提出的平台来估计目标角度和距离。

Space-Time-Coding Metasurfaces Enabling Programmable Range-Angle-Dependent Energy Auto-Scanning

This paper presents a novel energy auto-scanning system based on a space-time-coding metasurface. By applying progressive time-delayed, time-varying phase modulation, the system generates non-uniform, temporally evolving electromagnetic field distributions across both angle and range. Furthermore, a single-channel positioning system leveraging the MUSIC algorithm is demonstrated to estimate target angles and ranges using the proposed platform.
