摘要

将近乎完美匹配层(NPML)应用于三维弱混合隐显有限差分时域(HIE-FDTD)方法。在较弱的HIE-FDTD方法中应用拉伸坐标变量，可以得到所提出的HIE-NPML-FDTD算法的表达式。数值仿真结果表明，该算法具有弱条件稳定性和精度。

The Application of Nearly PML for a Weaker HIEFDTD Method

Nearly perfectly matched layer (NPML) is applied to a 3-D weaker hybrid implicit-explicit finite difference time domain (HIE-FDTD) method in this paper. By applying stretched coordinate variables in the weaker HIE-FDTD method, the formulation of the proposed HIE-NPML-FDTD algorithm can be obtained. The numerical simulation results show that the proposed algorithm is weakly conditional stable and accurate.
