Study on Reflection of Dust Plasma in Polar Mesosphere to Electromagnetic Wave

Abstract

Based on Boltzmann function and the generalized Ohm's law, the influence of charging on dielectric constant and electric conductivity are analyzed. Formulas of the dielectric constant and electric conductivity of dust plasma, which are applied to high frequency electromagnetic (EM) wave, are obtained. With the relative formulas and propagation characteristics in isotropic medium, the reflection coefficient of polar mesosphere where PMSE phenomena is observed is presented by using ECT02 experimental data. The relation between the characteristics of dust plasma in mesosphere and altitude is discussed, and the reflection profile changing with altitude is given.
