Cobalt-coated barium titanate particles: Preparation, characterization and microwave properties

Flexible composite film of aligned polyaniline grown on the surface of magnetic barium titanate/polyvinylidene fluoride for exceptional microwave absorption performance

“…14 Therefore, magnetic functionalized BaTiO 3 materials that combine dielectric and magnetic losses have attracted considerable attention and have been extensively studied to improve their microwave absorption performance. 15,16 Wang et al fabricated BaTiO 3 /Ni hybrid particles with a minimum reection loss (RL) of À14.9 dB at 13.6 GHz, and a frequency bandwidth of <À5 dB over nearly the entire Kuband with a thickness of 1.2 mm. 17 Qing et al prepared BaTiO 3 / carbonyl iron composites with a minimum RL of À42 dB at 4.1 GHz and a thickness of 2 mm.…”

Α-Fe /Nd₂Fe₁₄B Nanocomposites for Electromagnetic-Wave-Absorber in GHz Microwave Frequencies

“…However, electromagnetic interference (EMI) has become serious. One promising technique to prevent EMI is the use of microwave absorption materials [2][3][4]. However, the applications of conventional microwave absorption materials are limited.…”
