Solving the Complex Wire-Surface Junction Problems Based on An Accurate and Stable Time Domain Integral Equation Method
摘要
Abstract
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 mount-ed 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 .关键词
