摘要
提出一种基于FDTD的由粗到细网格逐步逼近计算电磁场的方法,并应用于内置带裂缝的金属谐振腔的电磁场的计算。结果表明:该方法与标准FDTD方法计算电磁场的精确度一致,但计算时间则明显少于后者。
A coarse-to-fine multi-grid approach for calculating electromagnetic field with FDTD is proposed and applied to calculate the time-harmonic electromagnetic field in the presence of a PEC resonant structure with a split. The obtained results are as the same accuracy as those ones achieved with a conventional merely fine grid FDTD run. But the running time is much lesser than the latter.
