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.
