A three-dimensional graphene/Fe3O4/carbon microtube of sandwich-type architecture with improved wave absorbing performance

Controllable synthesis of porous C x N y nanofibers with enhanced electromagnetic wave absorption property

“…The RL peaks shift from high to low frequency with the increase of sample thickness, and the RL becomes stronger. The minimum RL reaches −38 dB at 2.6 GHz and the absorption band below −10 dB covers from 2 GHz to 12.5 GHz, indicating its feasible application as stealth materials of both S, C, X and KU-bands [38].…”

Anti-oxidation mechanism investigation of SiO<sub>2</sub>+SiC+Al (H<sub>2</sub>PO<sub>4</sub>)<sub>3</sub> coating for continuous SiC fiber reinforced AlPO<sub>4</sub> composites with multi-walled carbon nanotubes as the absorber

“…Electromagnetic wave absorbing materials, designed to decrease reflected electromagnetic radiation by absorbing electromagnetic waves and transforming it into other energy, is a topic of extensive interest in the aerospace and military fields [1][2][3][4][5][6][7][8]. Currently, the research for applications in high-temperature environments is the main topic for electromagnetic wave absorbing materials.…”

Flexible Fe3Si/SiC ultrathin hybrid fiber mats with designable microwave absorption performance

“…Therefore, defects 18,19 or second phase additions (e.g. nanocarbon phase, [20][21][22][23][24] ZnO nano-crystals, 25 Al doping 26 ) are usually introduced to enhance the permittivity of 1D SiC nanomaterials, achieving a proper impedance match degree for microwave absorption properties. In particular, magnetic phase doped 1D SiC nano-materials, such as Fe-SiC whisker, 19 Fe 3 O 4 -SiC hybrid nanowires, 27 and Co-SiC hybrid nanowires, 28 could effectively improve the EM absorption performance by introducing both dielectric and magnetic losses.…”
