Abstract
To reduce electromagnetic (EM) wave interference pollution,in this work,carbon fibers@Co-ZIFs deriva-tions (CFZD) as an advanced EM wave absorbing material was successfully prepared.The yolk-shell struc-ture of the magnetic metal particles generated a large amount of contact area,facilitating the interface polarization and relaxation.As a result,the optimized sample delivers a maximum reflection loss (RL)value of-19.2 dB with a bandwidth of 2.6 GHz at a small thickness of 1.3 mm.Additionally,ANSYS Elec-tronics Desktop 2018 (HFSS) was used to simulate the radar cross section (RCS) reduction in practical application based on these composites.The RCS values of composite coatings are less than-10 dB m2 at the range of-90° ＜theta＜-10° and 10° ＜theta＜90°,which indicate the effective reduction of the radar reflection signal by the composite coatings.The work is of reference significance for preparing great ab-sorbing materials and designing absorbing coatings by combining simulation method.
