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

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
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.
