摘要
P-doped FeCo microcubes are fabricated through a facile solvothermal method using sodiumphosphinate (NaH2PO2 center dot H2O) as assisted agent. The morphology and particle size of FeCo alloy can be well controlled by tuning the NaH2PO2 center dot H2O amount. Benefitting from the unique morphology and the incorporation of P dopants, P-doped FeCo microcubes exhibit outstanding electromagnetic wave absorption performance with reflection loss of -51.67 dB at a very thin layer thickness of 1.60 mm, which is superior to the previously reported FeCo-based absorbers. The radar cross section (RCS) of FeCo as an absorber is simulated in the frequency of 2.0-18.0 GHz for the first time, which indicates that the RCS reduction effect is evident in a wide band, and the most significant decline in RCS is from -2.67 to -16.53 dBm(2) for horizontal polarization, and from -2.51 to -15.67 dBm(2) for vertical polarization. This work presents an outstanding electromagnetic wave absorbing material, and systematically analyzes the contribution of magnetic absorber to the reduction of RCS, which provides a reference for the practical application of magnetic absorbing materials.
