粒子在胞(PIC)模拟方法已被证明是研究等离子体与无线电波相互作用的一种很好的方法。然而，对于频率较低的混合频率范围内的波，完整的PIC模拟由于其计算成本较高而效率不高。本文采用回转动能电子和全动能离子(GeFi)粒子模拟模型，研究了低杂波在等离子体中的传播和模式转换过程。该方法采用较大的网格尺寸和时间步长，大大提高了低杂波模拟的计算效率。通过与线性理论的比较，验证了线性区域的仿真结果。
Particle-in-cell (PIC) simulation method has been proved to be a good candidate to study the interactions between plasmas and radio-frequency waves. However, for waves in the lower hybrid range of frequencies, a full PIC simulation is not efficient due to its high computational cost. In this work, a gyro-kinetic electron and fully-kinetic ion (GeFi) particle simulation model is applied to study the propagations and mode conversion processes of lower hybrid waves (LHWs) in plasmas. With this method, the computational efficiency of LHW simulations is greatly increased by using a larger grid size and time step. The simulation results in the linear regime are validated by comparison with the linear theory.
