Radio‐Frequency Front‐End‐Free Hybrid Code‐Division and Space‐Division Wireless Multiplexing Using Space‐Time‐Coding Metasurface

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
This work constructs a radio‐frequency front‐end‐free hybrid code‐division and space‐division‐multiplexing wireless communication system built on programmable space‐time‐coding metasurfaces. Orthogonal pseudo‐random codes reliably separate overlapped multistream signals that share identical frequency, time, and spatial resources.
