Application of EFIE to study skin current of aerial shielded cable excited by electromagnetic pulse

The time domain electric field integral equation (EFIE) is an important method in describing the radiation and scattering of electromagnetic. The method can be implemented with great efficiency in numerically simulation for the reason of mesh division can be made in scattering region instead of whole computational domain. The EFIE method is used to study the distribution of skin current and the characteristic of waveform in aerial shielded cable excited by EMP in this paper. The problems are studied experimentally in the radiated EMP simulator. The numerical data agree with the experimental results very well, and is of higher precision and trustily.
