- The absorber has excellent corrosion, wear resistance and soft-magnetic properties.
- The reflection loss reaches â60.3 dB at 7.08 GHz for the composite(30 vol % filler).
- Dual absorption peaks appear beyond 4.01Â mm for the composite(30Â vol % filler).
- This absorbing material has potential X-band application.
The FeCrMoNiPBCSi amorphous alloy system with good soft-magnetic property and high glass forming ability was utilized to prepare amorphous powders which are integrated for electromagnetic wave absorbing composite with silicone-matrix. The absorption parameters were measured by tuning the sample thickness and volume fraction strictly. The results show that FeCrMoNiPBCSi amorphous alloy system is more prone to attain impedance matching and has strong ability on electromagnetic wave attenuation. The value of reflection loss reaches â60.3 dB at 7.08 GHz for the composite (30 vol % powders) and the bandwidth reaches 2.30 GHz for RL  < â10 dB.
