Propagation characteristics of a high‐power electromagnetic wave through an inhomogeneous magnetized plasma is investigated. Considering the momentum transfer equations for electrons and ions and taking into account the ponderomotive force, the distribution of electron density and dielectric permittivity are obtained. Using non‐linear dielectric permittivity and Maxwell's equations in the absence of external current and charge densities, non‐linear wave equations are achieved. The results indicate that the external static magnetic field can modify the profiles of both the electric and magnetic fields. It is also shown that the external static magnetic field enhances the amplitude of the electron density and the non‐linear dielectric permittivity.

大功率电磁波与非均匀磁化等离子体相互作用中电子密度的增强

研究了大功率电磁波在非均匀磁化等离子体中的传播特性。考虑电子和离子的动量传递方程，并考虑到磁势，得到了电子密度和介电常数的分布。在没有外部电流和电荷密度的情况下，使用非线性介电常数和麦克斯韦方程，可以得到非线性波动方程。结果表明，外部静磁场可以同时改变电场和磁场的分布。还表明，外部静磁场会增强电子密度的幅度和非线性介电常数。
