| 摘 要： | 提出了一种将时域积分方程(time domain integral equation, TDIE)方法和时域有限差分(finite differnce time domain, FDTD)方法相结合计算分层有耗半空间上方导线瞬态电磁响应的新方法.其中,一维FDTD方法用于计算入射电磁波经分层半空间反射的时域波形.TDIE用于求解细导线在加入两个激励源(直接入射电磁波和经分层半空间反射的电磁波)时的瞬态响应.相关计算理论和数值模拟结果说明了本文方法是一种解决了分层有耗介质上方水平放置导线瞬态响应的高效解决方案.

| Abstract: | A novel hybrid method combining time domain integral equation(TDIE) with finite difference time domain(FDTD) is proposed to calculate transient response of thin wire structure above a layered lossy half-space. The time domain reflections of electromagnetic waves from layered half-space are obtained by one-dimensional FDTD method. Then, transient response of thin-wire induced by two excitation sources (incident wave and reflected wave) is achieved by employing the TDIE. The computed results illustrate the feasibility and high efficiency of the presented scheme. |
