Abstract

The analysis for lightning current facing in communication system has been analyzed and discussed in literatures. But the most of them are the situations of perpendicular to the ground for the lightning current, which is not universal. In this thesis, lightning current is simplified into a model of spatial diagonal current source, and `image method´ is adopted in the analysis of electromagnetic field distribution. The results show that lightning would create strong electromagnetic radiation when lightning occurs. This method provides a theoretical basis for further analysis of lightning protections.
