摘　　要：采用导电纤维对电磁波衰减的理论模型,对短切碳纤维在3mm波的干扰效果进行理论计算,并在微波暗室中及野外测试了短切碳纤维对3mm波的干扰效果。结果表明:最佳纤维长度为(2±0.5)mm,最大衰减能力超过-20dB。Based on the theoretical model of the electromagnetic wave attenuation by conductive fibers, the interferential effect of short carbon fibers at 3mm wave was calculated and tested, in the microwave darkroom and outdoors. The results showed that the optimum length of fibers is (2±0.5)mm, the maximum attenuation effect can exceed -20dB.
