基于瑞利散射理论，通过求解带电沙粒的散射场，揭示了沙尘暴对不同能见度电磁波传播的影响。由于沙子表面的电荷，在一定条件下理论衰减将足够大以匹配测量值。结果表明，表面布满电荷的沙子对电磁波的衰减效果与不带电荷的沙子的电磁波衰减效果相同，证明了电荷确实分布在沙子的部分表面。
Based on the Rayleigh’s scattering theory, the effects of sandstorms on the propagation of electromagnetic wave with different visibilities are presented by solving the scattering field of charged sand particles. Because of the electric charges on the sand surface, the theoretical attenuation will be large enough to match the measured value under certain conditions. And the results show that the effect of sand with electric charges all over its surface on electromagnetic wave attenuation is the same as that of sand without charge, which proves that electric charges distribute on partial surface of the sand in fact.
