| Abstract: |
| Objective To research microwave attenuation characteristics in charged sand and dust. Methods According to Mie scattering theory for a charged spherical particle, the scattering of charged sand and dust particle and attenuation properties for a medium with charged sand and dust particles were investigated. Results At the same frequency, the normalized extinction cross section increased with increase of particle radius size. The extinction coefficient of charged sand particles was greater than that of uncharged sand particles. The attenuations induced by charged sand and dust particle were greater than those of uncharged sand, and wave attenuation decreased with the increase of visibility. Conclusion The effects of charged dust particles on microwave propagation are more obvious than those of neutral dust particles. |
