Analysis of the Influence Factors of the Monocone Electric Field

In order to reduce the end reflection of the monocone, the influence of cooper bar radius and resistance value on electric fields were analyzed using genetic algorithm. The waveforms of electric fields were compared before and after optimization both using the Gaussian pulse and HEMP pulse as the excitation pulse source. The results show that when the excitation source is Gaussian pulse, the optimized return loss is less than −30 dB in the full frequency range; when the excitation source is HEMP pulse, within pulse width, the maximum of reflection electric field reduced by a factor of 1 compared with the monocone before optimization.
