Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

open access: yesCarbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...

Spider Silk Inspired Shape Adaptive and Heat Conductive Thermal Interface Materials

open access: yesElectron, EarlyView.
Inspiring by the architecture of spider silk, a semicrystalline PVDF polymer emerges selective crystallization by dipole polarization of amorphous chains while maintaining crystalline domains with exceptional thermal conductance. This precisely orchestrated hierarchical architecture optimizes thermal conductance by efficient phonon transmission along C–

Scale‐Invariant Waveguiding in Flatland

open access: yesExploration, EarlyView.
The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology

open access: yesInfoScience, EarlyView.
Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored
