The kinetics is analyzed of the drift of non-potential plasma waves in spatial positions and wavevectors due to plasma’s spatial inhomogeneity. The analysis is based on highly informative kinetic scenarios of the drift of electromagnetic waves in a cold ionized plasma in the absence of a magnetic field (Erofeev 2015 Phys. Plasmas 22 092302) and the drift of long Langmuir waves in a cold magnetized plasma (Erofeev 2019 J. Plasma Phys. 85 905850104). It is shown that the traditional concept of the wave kinetic equation does not account for the effects of the forced plasma oscillations that are excited when the waves propagate in an inhomogeneous plasma. Terms are highlighted that account for these oscillations in the kinetic equations of the above-mentioned highly informative wave drift scenarios.

强迫振荡对非均匀等离子体中波漂移动力学的影响

分析了由于等离子体的空间不均匀性而引起的非势等离子体波在空间位置和波矢上的漂移动力学。该分析基于在没有磁场的情况下冷电离等离子体中电磁波的漂移（Erofeev 2015 Phys。Plasmas 22 092302）和冷磁化等离子体中长朗缪尔波的漂移（Erofeev）的高信息动力学方案。 2019 J.等离子体物理学.85 905850104）。结果表明，波动动力学方程式的传统概念并未考虑到在非均匀等离子体中传播时激发的强迫等离子体振荡的影响。突出显示了在上述高度有用的波漂移方案的动力学方程中解释这些振荡的术语。
