Numerical Simulation Of Two-Stream Instability Induced By Equatorial Electrojet

The equatorial ionosphere is the most active region in the Earth's space, where the E region irregularities are a common phenomenon. The two-stream instability excited by equatorial electrojet is the main reason for the formation of E-layer irregularities. The particle-in-cell (PIC) method is used in this paper to simulate the evolution process of the two-stream instability. The energy variation curve and the growth rate curve of the two-stream instability are both analyzed. In addition, the excitation strip of the instability is simply analyzed.
