Abstract:Impedance matching and microwave attenuation play key roles in electromagnetic absorption. Moderate electromagnetic parameters will lead to matched impedance matching and attenuation ability. Using magnetic/dielectric composites is considered to be an efficient strategy for achieving excellent electromagnetic absorbing properties. The Co@C reported in this research not only resulted in improved impedance matching behavior, but also possessed strong microwave attenuation ability due to its polarizing and conducting features. As a result, the effective absorption frequency of the optimal absorber covers 4.2 GHz under a thin coating layer of 1.4 mm. The attenuation mechanism has also been discussed in depth in this study.
