| 中文摘要 | 地面入射的大功率高频无线电波(泵波)和电离层等离子体之间的参数相互作用,能够引起静电波的激发,在一定条件下,产生不稳定性.本文用PIC静电粒子模拟方法,研究泵波与赤道电离层E区等离子体的相互作用.研究结果表明,泵波能够控制双流不稳定性的发生,在不同条件下,泵波对双流不稳定性起着稳定与不稳作用,模拟结果定性地与理论研究结果相符合,这为我们对不规则体产生的地面人工控制提供了依据. |
| 英文摘要 | Two-sueam ema instability is one of some typical instabilities occurred in iono-sphere. It exists in equatorial ionospheric and auroral ionospheric E region. Gener ally speaking,the two-stream instability appears occasionally due to the presence of a relative strong vertical electric field needed. In recent decades, several powerful High-Frequency (HF) radio wave transmitters were set up successively in the world, which provide us convenience to study the interaction of HF radio waves with plas-mas.For example, the parametric process between the powerful HF radio waves (pump waves) and the ionospheric plasma, which will excite the electrostatic waves, and some instabilities may be produced under special conditions.In this paper, one dimension PIC (Particle In Cell) electrostatic particle simulation is used to study the interaction of pump waves with the equatorial ionospheric E region. The simu- lation results show that pump waves can control the two-stream instability. With different parameters, the instability can be stabilized or destabilized by the pump waves. The results are consistent with the theoretical model qualitatively.The simulation studying provides the probabilities for artificial control the irregularities by very strong radio waves on the ground. |
