Numerical simulation and verification of electromagnetic pulse effect of PIN diode limiter

The electromagnetic pulse effect mechanism of PIN limiter is analyzed，and the devices multi-physical field model is established with software Sentaurus-TCAD. The input/output power curve, indicating the increase in flat leakage with increasing input power, is studied, and the simulation results are in good agreement with the experimental ones. The influence of electromagnetic pulse width on the diodes damage is simulated. Adopting the data analysis software, the relation equation between the device damage power and the pulse width under different injecting power is obtained. It is analyzed using Wunsch and Bell developed semi-empirical relationships.
