膨胀石墨的毫米波二维平面散射截面研究

本文报道了不同平面密度下或不同长度的膨胀石墨蠕虫的毫米波二维平面散射截面的实验结果，并将其与镀铝玻璃纤维和铝箔条的相关实验结果作了对比研究。结果表明，膨胀石墨蠕虫虽然在物理形状上与镀铝玻璃纤维和铝箔条有相似之处，并且具有一定的导电性能，但其对毫米波的散射特性并不符合半波谐振子模型所推导的结论，且其毫米波散射截面远远小于镀铝玻璃纤维和铝箔条。

Study on Two Dimensional Planar Millimeter Wave Scattering Cross Section of Expanded Graphite

Two dimensional planar millimeter wave scattering cross section of expanded graphite worm which was measured at different planar desities or length was reported in this paper.The experimental result was compared with that of aluminium coated glass fibre and aluminium chaff.Although the expanded graphite worm has a fairly highelectrical conductivity,and the shape of expanded graphite worm is similar to that of aluminium coated galss fibre and aluminium chaff,but the millimeter wave scattering characteristic is not corresponded with the conclusion which can be deduced from half-wave harmonic oscillator model.And the millimeter wave scattering cross section is more smaller than that of aluminium coated glass fibre and aluminium chaff.
