Abstract

A frequency-advantage to layer-stacked rule was proposed to design the wide band absorbing materials. The two stacked layer was constructed by the silicone rubber composites added the FeSi alloys and the carbonyl iron particles (CIPs). The layer permittivity and permeability were measured using a vector network analyzer, and then the reflection loss (RL) and the shielding effectiveness (SE) of the two type layer were calculated respectively. The results indicated that composites added FeSi had the higher permittivity and permeability at 1-4 GHz while the composites added CIPs had the better absorbing property at 8-18 GHz due to the characteristics of the two absorbents. Then using a genetic algorithm method on optimizing the wide frequency, the absorbing property of the two advantage frequency could be kept. The absorbing band was widened to 2.3-18 GHz as RL was lower than -8 dB with the total thickness less than 3 mm. The frequency-selected to layer-stacked rule was an effective method on designing the absorbers with the wide frequency absorbing band.
