摘　　要：时域电场积分方程是研究电磁辐射及散射等问题的重要方程。在数值计算中,该方程方法只需将散射体进行剖分,而不必将剖分推至整个计算域内进行,计算效率较高。将时域电场积分方程方法引入到电磁脉冲作用下架高屏蔽电缆蒙皮电流的计算中,研究了电缆的蒙皮感应电流分布及波形特征。通过与辐射波电磁脉冲模拟器的实验结果的比对,证明了数值结果的可靠性。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. 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.
