Microwave absorption properties of planar-anisotropy Ce2Fe17N3−δ powders/Silicone composite in X-band
چکیده انگلیسی
The soft-magnetic properties of planar-anisotropy Ce2Fe17N3-δ powders were reported, and reflection loss (RL) of the powders/Silicone composites with various volume concentrations have been studied in 0.1-18 GHz frequency range. It was found that the optimal RL of this composite absorber with a thickness of 1.72 mm is −60.5 dB at 9.97 GHz and the RL is less than −10 dB in the whole X-band (8-12 GHz). The bandwidth with RL exceeding −10 dB and −20 dB are 5.24 GHz and 1.32 GHz, respectively. Furthermore, all the optimal RL value of the composite with the thickness less than 2.13 mm can reach −20 dB in the range of 8-17 GHz, which indicates that the Ce2Fe17N3-δ/Silicone composite absorber will be a promising candidate in higher gigahertz frequency especially in X-band.
