【摘要】 为了更好的求解电磁场复杂边界问题和局部细化问题,研究了基于混合单元的电磁场时域有限积分方法。将该方法应用到数值求解理想圆波导对应于某一模式截止频率的问题上,和时域有限差分方法相比,能够在不增加较多节点和单元数的条件下,得到较高精度的解。更多还原

【Abstract】 In order to deal with the complicated boundary problem and the local refinement problem in electromagnetic field, the Finite Integration Technique(FIT) method based on mixed cells was studied.This method was applied to get the cutoff frequency of ideal circular waveguide corresponding to one mode.It is more accurate than FDTD method without the need of many nodes and cells.更多还原
