摘要
The natural resonance appears at 16 GHz for (Fe, Ni)/C nanocapsules with (Fe, Ni) alloys as cores and graphite as shells. Reflection loss (RL) exceeding -10 dB was obtained in the whole Ku-band (12.4-18 GHz) for an absorber thickness of 2.0 mm, while it exceeds -20 dB over the 13.6-16.6 GHz range. In addition, the bandwidth does not change dramatically for the thicknesses of 1.87-2.1 mm for the RL values exceeding -10 dB. The (Fe, Ni)/C nanocapsules with wide bandwidth absorption can be used as excellent electromagnetic-wave-absorption materials in the whole Ku-band. (C) 2008 Elsevier Ltd. All rights reserved.
