摘要/Abstract

摘要： 利用镍粉和乙烯基酯树脂制备吸波复合材料,设计并制备了双圆柱吸波层,与频率选择表面(FSS)复合,得到基于频率选择表面的吸波材料,研究了吸波材料在1~18GHz范围内的电磁波反射率。结果表明,吸波材料电磁波反射率的实验值和仿真值基本一致,当镍粉含量为35%时,第一吸收峰在6.2GHz处,峰值为-22.3dB,-8dB以下带宽为4.7GHz;当镍粉含量为45%时,第二吸收峰-8dB以下的带宽为8.5GHz。

Abstract: In this paper, nickel powder and vinyl ester resin were used to prepare absorbing composite material, and double cylindrical absorbing layer was designed and prepared to compound with the frequency selective surface (FSS) to obtain an absorbing material based on FSS. The microwave reflectivity of the absorbing material was tested between 1 GHz to 18 GHz. It is found that the experimental values of reflectivity for microwave absorbing materials are in agreement with the simulation results. The first absorption peak at 6.2 GHz is -22.3 dB, and the bandwidth under -8 dB is 4.7 GHz when the content of nickel powder is 35 wt% when the content of nickel powder increases to 45 wt%, the bandwidth below -8 dB for second absorption peak is 8.5 GHz.

Key words: microwave absorbing materials, double-layer cylinder, frequency selective surface (FSS), nickel powder
