摘　　要：为提高材料的吸波性能和拓宽吸波频带,选择ZnO和FeNiMo颗粒作为吸收剂、石蜡作为粘结剂制作吸波材料,采用矢量网络分析仪测试材料的电磁参数,并在给定厚度2mm下分析吸波材料的吸波性能。实验表明：ZnO可以显著降低FeNiMo的介电常数,有利于使其作为电磁波吸收材料使用时达到阻抗匹配;当吸波材料的厚度为1.5mm,ZnO颗粒的含量为50wt%时,吸波材料的吸收峰R在15.98GHz时达到最小值,其值为-27.1dB,在13.46-18GHz频段内低于-10dB,具有较好的吸波效果。In order to increase the absorbing ability and expand the absorbing bandwidth,ZnO and FeNiMo particles were established as absorbers,and wax as adhesive,and the electromagnetic parameters were tested by using a vector network analyzer,then the absorbing properties were calculated with a given thickness（2mm）.Experiments show that ZnO can significantly reduce the dielectric constant of FeNiMo,which is beneficial for reaching the impedance matching as an electromagnetic wave absorbing material.And the mixing powder with 50% mass fraction of ZnO powder has excellent microwave absorption properties of a thickness of 1.5mm and a broad absorption bandwidth of 13.46-18GHz（R〈-10dB）.
