摘要
根据无耗介质中电磁波电场与磁场值在任一时空点上的定值阻抗比,得出了一种新型FDTD吸收边界条件——定值阻抗吸收边界,并将其与二阶Mur吸收边界进行了比较,结果表明是一种简明而有效的边界吸收方法。
Based on the fixed impedance ratio of the electric and magnetic fields for electromagnetic wave travelling in lossless medium,a new absorbing boundary condition is derived. The examination results of FDTD for the comparison between the method and the Mur’s ABC are given,It is shown that the method presented has an advantage,and it is a compendious and effective absorbing boundary condition.
