一致性绕射理论加速的时域积分方程方法

A UTD Enhanced TDIE Algorithm

为计算电大平台上天线间的互耦提出一种一致性绕射理论加速的时域积分方程算法。引入一致性绕射理论中射线寻迹的方法,对占时间步进法主要计算量的迟滞积分项进行加速,以牺牲部分精度为代价,提高了时域积分方程算法的计算速度。数值算例证明了有效性。

For antenna coupling problems on electrically large platforms,a uniform theory of diffraction（UTD） enhanced time domain integral equation（TDIE） algorithm is proposed.The computational time consumed in marching-on in time（MOT） solver is reduced by introducing the idea of UTD,the computation of TDIE is accelerated at the cost of losing some precession,and numerical results prove the validity.
