摘要：

Marching-on-in time (MOT) method is used to solve the time domain surface-wire integral equation (TDSWIE), so that we can solve complex problems, such as wire antennas mounted on the perfect electrically conducting (PEC) surfaces, etc. In order to improve the late-time stability of the method, an efficient scheme based on accurately calculating the elements of the impedance matrix is adopted. In the numerical simulations of a dipole antenna mounted on a PEC sphere and a spiral antenna mounted on a PEC antenna pedestal, the transient surface current, S11 parameter, the input admittance and the directivities of the antennas are obtained. Numerical results demonstrate the efficiency and accuracy of this method.
