The influence of ice particles on microwave propagation in thundercloud

Based on the scattering model of charged particles to electromagnetic waves in Rayleigh approximation and permittivity model of ice particles, we deduced the attenuation model under the situation when the electromagnetic waves pass through ice particles area, then we performed the simulation and made analyses. The results show that: (1) When the ice particles are electrically charged, the attenuation of electromagnetic waves is much greater than those who are not charged. (2) The more charge of ice particles, the greater effect it will make on the attenuation of electromagnetic waves. (3) The frequency of the electromagnetic waves also has a great influence on the attenuation, the higher the frequency, the greater the attenuation.
