One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide
Advanced Physics Research, EarlyView.This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...

Broadband Conductance Matching Effect in Conductive Metamirrors
Advanced Physics Research, EarlyView.A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.
