Full-wave analysis of the EMP induced current in cables near the ground

The finite-difference time-domain (FD-TD) method is applied to the analysis of the EMP induced cortical current in coaxial cables near the ground in this paper. This method is a kind of full-wave analysis method. Not only transmission line current but also aerial current is considered in the calculation of induced current. This method is used to analyze all kinds of cortical induced current. The result in this paper is reasonable compared to relative data.
