    Abstract
  • Polar Mesosphere Summer Echoes (PMSE) will disappear immediately under the condition of high power microwave irradiation, which is called heating phenomenon in the polar mesosphere. When the high power microwave irradiate the polar mesosphere, the directional motion velocity of the electrons under the acceleration of microwave electric field can be compared with the thermal motion velocity, and the dust plasma in the polar mesosphere obeys the dual Maxwell distribution. The charge distribution of dust particles in the polar mesosphere is given based on the charge theory of dust particles under double Maxwell distribution. The charge changes of dust particles and the electron concentration are compared before and during the high power microwave heating the polar mesosphere. The results show that heating the polar mesosphere with a high-power microwave device will affect the charge of electrons to dust particles and lead to the change of electron concentration, which is of great significance to further explain the phenomenon of heating in the polar mesosphere.
