摘要
从常规Mur吸收边界条件的推导出发 ,引入有耗介质的相应参数 ,使其可应用于截断边界电磁参数不连续和介质为有耗的情形。通过模拟公式计算 ,并与常规Mur吸收边界条件对比 。
Starting from the derivation of conventional Mur absorbing boundary conditions, co esponding parameters of lossy media are introduced, which are used for the discontinuity of sectional boundary electromagnetic parameter and cases of lossy media. The result of simulated equation calculation is contrasted with that of conventional Mur absorbing boundary conditions, which shows that the modified Mur absorbing boundary conditions are superior and suitable for lossy media.
