【摘要】 本文报道了不同长度膨胀石墨蠕虫的毫米波二维平面衰减实验结果 ,并将其与传统的微波干扰材料———铝箔条的毫米波衰减性能作了对比研究。结果表明 ,尽管膨胀石墨蠕虫在物理形状上与铝箔条有相似之处 ,并且具有一定的导电性能 ,但其对毫米波的衰减特性并不符合半波谐振子模型所推导出的结论。膨胀石墨蠕虫对毫米波的衰减为散射和吸收作用的综合结果。更多还原

【Abstract】 Two dimensional planar millimeter wave attenuation characteristic of different length expanded graphite worms was reported in this paper.The experiment result was compared with that of chaff which is a conventional microwave interference material.Although the expanded graphite worm has a fairly high electrical conductivity,and the shape of expanded graphite worm is similar to that of chaff,but the millimeter wave attenuation characteristic is not corresponded with that of chaff which can be deduced from half\|wave harmonic oscillator model.The millimeter wave attenuation of expanded graphite is a comprehensive actions of scattering and absorption.更多还原
