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 ...

Coupling of 0D/1D Grain Boundaries Inducing Extreme Charge Rearrangement/Magnetic Resonance for Ultrabroadband Electromagnetic Wave Absorption

Carbon Energy, EarlyView.
The 0D/1D grain boundary coupling between Fe₃O₄ quantum dots and CNTs induces extreme charge redistribution and short‐range magnetic resonance, enabling complete electromagnetic wave absorption across the entire X and Ku bands. ABSTRACT Ferrite–carbon composites effectively absorb electromagnetic (EM) waves via coupled mechanisms.
