In this article, we present a first-principles electromagnetic–kinetic simulation of the slow-wave branch of the lower hybrid waves (LHWs) in electron–deuterium plasmas with real ion–electron mass ratios. Several models of two-dimensional slab configuration containing a grill antenna are constructed using different plasma parameters. Based on our recently developed fully kinetic charge-conservative electromagnetic non-canonical symplectic particle-in-cell method, we studied the coupling, propagation, absorption and current driving effect of LHWs in hot plasmas. The results for the coupling coefficient of the grill antenna, accessibility condition, and electron Landau damping rate show good agreement with theory and previous simulation. The long-term non-linear energy and current deposition of propagating LHWs are also presented, which show a decrement of heating and current-driving efficiency compared with the linear theoretical prediction. The collision effect between electrons and ions is shown to be important for actually driving the current. The relation between the density of the current generated and the amplitude of the LHW is given, which shows a qualitative agreement with the 1D theoretical prediction.

在本文中，我们给出了具有真实离子-电子质量比的电子-氘等离子体中较低杂化波（LHW）的慢波分支的第一性原理的电磁动力学模拟。使用不同的等离子体参数构造了包含格栅天线的二维平板结构的多个模型。基于我们最近开发的完全动态电荷守恒的电磁非规范辛格在胞内粒子方法，我们研究了热等离子体中LHW的耦合，传播，吸收和电流驱动效应。格栅天线的耦合系数，可及性条件和电子朗道阻尼率的结果与理论和先前的仿真结果吻合良好。还介绍了传播的LHW的长期非线性能量和电流沉积，与线性理论预测相比，它显示出加热和电流驱动效率的降低。电子和离子之间的碰撞效应对于实际驱动电流非常重要。给出了所产生电流的密度与LHW幅度之间的关系，这与一维理论预测在质量上具有一致性。
