| description | Because of the excellent properties, carbonyl iron powder particles and their surface modified products are often used as radar absorbers. The electromagnetic wave attenuation mechanism of the carbonyl iron powders and SiO2 coated carbonyl iron particles were analyzed on the basis of the studies of scholars from all over the world and compared with the solutions calculated by the COMSOL software. The results obtained through the analytical solution and COMSOL simulated calculation values tend to be consistent; the ratio of the complex magnetic permittivity to the complex permittivity of the nano-SiO2 coated carbonyl iron powder particles tend to be 1, and the impedance matching performance of nano-SiO2 coated carbonyl iron powder particles is improved. Compared with the carbonyl iron particles, SiO2 coated carbonyl iron particles have lower electromagnetic wave absorptivity. |
