摘要

Based on the method of moment (MOM) and marching on-in-time method (MOT), a new method to solve the time domain integral equation (TDIE) was put forward, which can be used to investigate the transient response of the complex electrical networks and those with lumped parameters electrical element effectively. With the axial currents on the metal conductors taken as unknown variables, and the piecewise linear function selected as basis function, the time invariant matrix is set up by applying subdomain match method. As the matrix inversion is removed from calculation process, the efficiency is improved significantly. Comparison of the results and those obtained by using the method of multi-conductor transmission lines (MTL) displays little difference. Finally, the proposed method, which is applicable to far field, is used to analyze the effect of a simplified reinforced concrete building on the lightning radiation magnetic field, and some useful results are obtained.
