摘要
根据色散媒质的性质及电磁波在两不同媒质交界面上反射的机理 ,证明并分析了在理想匹配层吸收边界中引入色散可实现有效吸收入射到吸收边界上的电磁波 。
Based upon properties of dispersive material and theory of electromagnetic wave reflection on the interface of two materials, it is found that material discontinuity is the cause of the invalidation of the general perfectly matched layer absorbing boundary conditions (PML ABCs) in dispersive materials. The effectiveness of dispersive perfectly matched layer absorbing boundary conditions is proved numerically, which helps to reduce computing spatial domain and calculation error of the finite-difference time-domain (FDTD) method.
