摘　　要：采用静态测试方法 ,研究了膨胀石墨对 3mm、8mm波衰减性能 ,并与传统的毫米波干扰材料一铝箔条进行了对比 .膨胀石墨对 3mm、8mm波衰减分别为 17.0dB和 16 .6dB ,而铝箔条分别只有 7.4dB和 4 .1dB ,表明膨胀石墨是一种较好的毫米波干扰材料 .同时 ,研究了膨胀石墨粒度 (直径及长度 )对衰减性能的影响 .并给出了最大衰减效果的最佳粒度范围 .The millimeter wave attenuation performance of expanded graphite at 3mm and 8mm wavelength was studied by static experiments. The comparative experiment using aluminium chaff, which is a kind of well known millimeter wave countermeasure material, was also done. The results show that the attenuation of expanded graphite at 3mm and 8mm wavelength are 17.0dB and 16.6dB respectively, and the attenuation of aluminium chaff are 7.4dB and 4.1dB. It means that the expanded graphite could be a better millimeter wave countermeasure material. the optimal particle size(including diameter and length) of expansive graphite that achieves the maximal attenuation was also obtained by experiments. These results could be a valuable reference for the design of full band screen smoke.
