Abstract Multifunctionalization of electromagnetic wave absorbing materials (EMWAMs) presents a promising avenue for their application in complex scenarios. However, the effective integration multiple supplementary functions into EMWAMs continues to pose significant challenge. Herein, novel nanofiber elastomer (NFE) incorporating multicomponent inorganic FeS 2 /S,N co‐doped carbon nanofibers (NFs) and organic component (Ecoflex) are designed synthesized. The sulfur doping ratios species can be effectively modulated via controlling amount sulfurization temperature. optimized NFs/Ecoflex NFE not only exerted an excellent impedance matching characteristic, but also displays boosted conductive loss polarization capacities. Amongst, achieved ultra‐wide absorption bandwidth (EAB) 7.40 GHz minimum reflection (RL min ) −21.82 dB at thin thickness (≈2.00 mm). Furthermore, simultaneously greatly improved mechanical property, thermal insulation, hydrophobicity, corrosion resistance. Through designing metastructures, with periodically closed‐ring resonant structure realized EAB 32.64 (ranging from 7.36 40.00 GHz). Overall, this research contributes valuable insights design next‐generation satisfactory multifunctionalities, demonstrating potential smart devices challenging environments.

One-dimensional iron–nickel (Fe–Ni) heterogeneous nanowires with superior electromagnetic wave (EMW) absorption were successfully prepared by a magnetic-field-assisted liquid-phase reduction method. The properties of the absorber controllably tuned changing atomic molar ratio Fe to Ni. composite an Fe:Ni 1:1.5 exhibited finest EMW characteristics. With matched thickness 2.175 mm, minimum reflection loss (RLmin) at 18 GHz can be as high 26.106 dB.

A metamaterial broadband absorber is designed by means of metal pattern and lumped resistance. The optimal structural parameters resistance are scanned in certain steps to determine. maximum absorbing bandwidth can achieve up 8.2 GHz with 3 mm thickness. Subsequently, the angle stability be improved adding vertical through holes. After optimization, further increased 9.1 (8.3–17.4 GHz), effective absorption 3.7 (9.53–13.25 GHz) still achieved when incident 60°. Further analysis reveals that dissipation electromagnetic wave ohmic loss caused resistive element magnetic resonance induced circular current, rather than temperature or other factors. Finally, verify real performance absorber, a 30 cm × sample was fabricated, reflection coefficient tested NRL arch test method. results showed measured return consistent simulation results.
