摘要
首先对媒质匹配条件进行了分析 ,得出时变媒质中电磁波无反射传播所需的参数关系 ,并将普通的Mur和PML边界拓展到时变媒质的FDTD分析中 ;根据时变媒质的特性 ,提出了由时变媒质构造的局部吸收负载 ,并对其应用进行了探讨。结果表明 ,此吸收负载具有灵活多变、简单便捷。
In this paper, media matched condition is firstly analyzed and the parameters' relation is obtained which needed for nonreflecting propagation in time varying media, then the common Mur and PML boundary conditions are expanded to FDTD simulation. According to the characteristics of time varying media, a local absorbing load is presented and analyzed, and the results show it has many advantages including agility, simpleness, high absorbing efficiency and so on.
