Abstract

NEC-2 code, a standard tool for numerical analysis on electromagnetic field around antennas, can be applied to analysis of lightning transient overvoltages. The code solves three-dimensional boundary problems by using the electric-field integral equation. This tutorial introduces the basic theory of NEC-2, and explains how to tune the original program to fit for time-domain analyses. Then the set up of the input data for a simple test case is described. The accuracy of the analysis is demonstrated by comparison with an experiment, and finally, results of advanced study are presented
