Study Of The Electromagnetic Wave Transmission Characteristics In Strong Ionization Complex Plasma

The related theory of complex plasma have been mature in the research and development of EM wave and plasma.The transmission of electromagnetic wave in plasma in space physics,experiment equipment manufacturing and industrial production has a wide application such as Such as rocket plume of the attenuation of electromagnetic wave,shuttle "black barrier effect"After putting the dust particles into the ordinary plasma,dusty particles will collide and charge with the charging particles in plasma so the transmission nature of EM wave will be changed.The research of complex plasma mainly focused on the plasma conductivity and the changing of dust particles charging current,etc but there are some blanks for the transmission characteristics of EM waves in the complex plasma.This article study microwave frequencies of electromagnetic wave in strong ionization complex transmission and attenuation characteristics of plasma from two aspects:the theoretical derivation and the use of Matlab simulation.We neglect the existence of the neutral molecules in the strong ionization complex plasma So we consider that the interaction between electron and ion is the main property of electromagnetic wave transmission.This article embarks from the boltzmann equation involving laudau collision term of statistical physics,using the theory of the basic theory of complex plasma with OML so that the particle movement characteristics are analyzed.This paper gives a strong ionization cases of complex plasma dielectric constant expression.Using a vacuum-plasma-vacuum idealized theoretical model of three layer medium,concentration of dust particles is given by the simulation calculation of the Mat,dust particle size distribution,dust particle relative charge on the influence of the parameters such as change of electromagnetic wave transmission properties and their reasons are analyzed.Through the study of this article we will further consolidate and improve the electromagnetic wave in strong ionization weak collision theory of complex plasma transmission properties,and the electromagnetic wave transmission in rocket plume,avoid "blackout" effect and better explain the polar middle summer echo play a positive role in promoting.
