| description | The development of stealth technology for military applications and increasing concerns of electromagneticpollution have garnered interest to design microwave absorbing materials with wide absorption bandwidth andeffective absorption properties. Two batches of samples as a potential radar absorbing material were prepared inthis study: single-layer and double-layer nanocomposite mixtures of graphite and barium hexaferrite nano-particles. Characterizations of electromagnetic and microwave absorbing properties were carried out in thefrequency range of 8−12 GHz (X-band) and 12−18 GHz (Ku-band). Single-layer samples with thickness of 2 mmshowed optimal absorption properties with minimum reflection loss of -20.5 dB at 11.8 GHz for X-band and-20.7 dB at 14.7 GHz for Ku-band, displaying bandwidths of 0.6 GHz for the former and 3.8 GHz for the latter at-10 dB. On the other hand, double-layer samples made of 1 mm thick barium hexaferrite matching layer and2 mm thick graphite absorbing layer showed optimal absorption properties with minimum reflection loss of-30.0 dB at 9.2 GHz for X-band with narrower bandwidth of 0.6 GHz. The microwave absorption properties ofthese nanocomposites were attributed to combined effect of dielectric loss from graphite and magnetic loss from ferrite. |
