Metasurface has aroused broad enthusiasm due to its splendid properties on electromagnetic (EM) wave manipulations. However, most of previous metasurfaces, including passive and active, are almost energy-losing in controlling the EM waves. Here, we propose a space-energy digital coding metasurface to...
Performance of the reconfigurable metasurface in 1-bit reflection and 1-bit transmission modes As previously mentioned, applying distinct electric field bias values at various locations across the proposed metasurface leads to a switchable coding layout that enables real-time manipulation of EM waves. Th...
In recent years, the proposal and development of time-domain coding metasurfaces (TDCMs) and space-time-coding metasurfaces (STCMs) have further enriched the electromagnetic modulation and digital process schemes and application scopes. However, most of metasurface-based wireless communication ...
