摘要

基于二维单元内粒子时域码的有限差分，讨论了高功率短脉冲激光与目标相互作用时EMP的产生。首先，模拟了激光脉冲与等离子体的相互作用，得到了热电子的信息。然后，模拟了逃逸电子在真空中运动产生电磁脉冲的过程。仿真结果表明，电磁场峰值为100kV/m，频率非常宽。

Simulation of electromagnetic pulse generation in laser-plasma interaction

Based on a 2D particle-in-cell finite difference in time domain code, the generation of EMP in the high-power, short-pulse laser interaction with the target is discussed. First, the interaction of laser pulses with plasma is simulated and the information of hot electrons is obtained. Then, the process that escaping electrons moving in the vacuum generates EMP is simulated. The simulation shows a peak electromagnetic filed 100kV/m and a very broad frequency.
