摘要
在FDTD应用中常常遇到复杂结构中的低频段仿真问题,如何选择激励源可能成为"瓶颈"问题。分析了该"瓶颈"现象,探讨了可用的选择方法,提出了一个关于低频激励源准则,并给出计算实例以支撑本文的观点。
In FDTD application, simulation at low frequency band for a complex structure is often met. In this case, how to choose an apropriate exciting source may become a bottle neck. This paper analyzes this bottle-neck phenomenon, discusses the method to solve the problem and presents a criterion on low frequency exciting source. Some calculation examples support the view in the paper.
