摘要	Electromagnetic-wave absorption properties of FeNiMo/C nanocapsules with FeNiMo nanoparticles as cores and carbon as shells have been studied. The FeNiMo/C nanocapsules, synthesized by arc-discharging Fe(11)Ni(79)Mo(10) (at.%) alloy in ethanol, exhibited outstanding reflection loss (RL < -20 dB) in the range of 13-17.8 GHz with an absorber thickness of 1.7 mm, and an optimal RL of -64.0 dB was obtained at 13.2 GHz with an absorber thickness of 1.9 mm. The broadest bandwidth (RL < -10 dB) from 9 to 18 GHz, covering the whole Ku-band (12.4-18 GHz) and almost the whole X-band (9-12.4 GHz), was achieved for a 2 mm layer. The excellent electromagnetic properties are ascribed to the good match between high permeability from the core of FeNiMo nanoparticles and low permittivity from the special core/shell microstructure in the FeNiMo/C nanocapsules.
