摘要

本文给出了一种逐级计算输电线路附近电磁场的方法。通过将传输线分解成若干赫兹偶极子，将每一段的贡献相加，就可以求得地面上任何一点的电场和磁场。本文采用两种解析频域方法计算了有限导电地面上水平电偶极子(HED)的辐射，并进行了比较。数值电磁码(NEC-4)用于验证结果。

Transient Electromagnetic Fields associated with a power transmission line above a lossy ground

This paper provides a step by step procedure for the computation of electromagnetic (EM) fields in the vicinity of power transmission lines. By decomposing the transmission line into a number of Hertzian dipoles, the electric and magnetic fields at any point above the ground can be found by summing up the contribution of each segment. Two analytical frequency-domain approaches for the calculation of radiation from a horizontal electric dipole (HED) located above a finitely conducting ground are implemented and compared. Numerical electromagnetic code (NEC-4) is used in order to verify the results.
