| Objective To put foward a numerical algorithm of transient response for short-wave monopole antenna in the external electromagnetic pulse based on time-domain integration method of moments. Methods To expand the time-domain coefficients of unknown current, the Gail polynomial was used for the basic funtion as the whole time-domain space, and the transient reponse of the monopole antenna was numericaly simulated. The results are compared and verified with experimental data. Results The method proposed in this paper match the data in experiment well.The effectiveness of the method is validated. Conclusion The method established the paper can be used as the input conditions for these antenna or system caused intentional elctromagnetic interference response and protection. |
