平面电磁波在无磁场等离子体中传播特性研究

The Research of Propagation Characteristics of Plane Electromagnetic Wave in Plasma without Magnetic Field

推证了无磁场时电子等离子体的等效介电系数,根据本构关系认为无磁场电子等离子体属各向同性介质.从色散关系得出等离子体中传播电磁波的相速、群速,并以此为依据对等离子体中传播的电磁波性质进行了分析.

This paper proves equivalent dielectric constant of electronic plasma and holds that electronic plasma belongs to isotropic medium from constitutive relation without magnetic field, it also gets phase velocity and group velocity of electromagnetic wave in plasma from dispersion relation and analyses properties of electromagnetic wave in electronic plasmas besed on phase veloctiy and group velocity.
