非均匀双流等离子体中波传播耦合波动方程

我们利用麦克斯韦方程组和矩方程组,研究了非均匀双流等离子体在电流源作用下,激发波的耦合过程。给出了三模P_e,P_i,E_o]耦合的普遍方程▽2P]-C]·▽P]+K2]P]=D]▽·(ω_p2E_o)]。作为一特例,本文首先研究了均匀、有损失(v≠0)双流等离子体中,等离子体波的耦合过程。指出v≠0,即使在均匀等离子体中,也将产生电子等离子体波和离子等离子体波间耦合。但不出现光学模和等离子体模间耦合。 

THE WAVE EQUATIONS FOR THE COUPLING OF PROPAGATION IN INHOMOGENEOUS AND BI-FLUIDS PLASMAS

On the base of the Maxwell equations and moment equations,this paper has investigated the Coupling Processes of the excited waves in an inhomogeneous and bi-fluids plasmas under the action of a Line Sourse and has Presented the general equation for the Coupling of three moduli (P_e,P_i,E) ▽2P]-C]·▽P]+K2]P]=D]▽·(ω_p2E_o)] As an example,we have studied the case of the coupling processes in a homogeneous,lossy (v≠0),and bi-fluids Plasmas,showing that even if the plasma is homogeneous,so long as v≠0,a coupling will take place between the electronic plasma wave and the ionic plasma wave,but no coupling will occur between the Optical modulus and the plasma modulus.
