Abstract—In this paper, we propose the computational model of plasma collision frequency based on the plasma particle component. The computational model of collision between electrons and neutral particles is validated through the parallel panel collision frequency experiment in which the electrons are simulated by the laser. The electromagnetic wave propagation experiment in plasma under the high temperature shock wave tube environment proves the effectiveness of plasma collision frequency model. Results from comparison between simulation and experiment indicate that the proposed method is able to provide comprehensive description of multi-component plasma collision phenomenon and high accuracy in the collision frequency computation among electrons, ions and neutral particles. The research achievement is helpful applied to evaluate the effect of plasma collision absorption.
