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.

Abstract The modulation of transport properties in ceramic‐based semiconductors can be used to optimize the electromagnetic response mechanism and performance. A semiconductor ceramic foam interlayer wall (SCFW) is designed by a physical vapor deposition method. structural SCFW composed semiconductor‐insulator‐semiconductor layers, incorporating composite system SiC, Al 4.8 Si 1.2 O 9.6 , 2 3 . Moreover, hierarchical network structure controlled pyrolysis‐deposition kinetic process. Electrons holes are transported through heterojunctions between SiC achieving effective charge relaxation. matrix provides lightweight (density 0.967 g cm −3 ), while determines excellent wave (EMW) absorption performance SCFW, with an bandwidth up 14.8 GHz under (minimum reflection loss RL min = −50.6 dB). has been proven exhibit corrosion resistance thermal insulation properties, conductivity 0.025 W m −1 K This study valuable insights into design dielectric property optimization nanocomposites, which leads strong polarization loss, opening new avenues for application EMW absorbers, ceramics.
