摘要
给出了三维ADI-FDTD的数值色散关系式。沿空间步长最大的方向,实现了对三维色散关系的降维处理,使色散分析变得容易。并利用降维的方法,对三维ADI-FDTD的数值色散关系进行了全面的分析,得出相关的结论。
It explains a numerical dispense relationship in the three-dimensional ADI-FDTD method,a dimension deducting can be made along the direction of a maximum space-step length in regard to dimensional distension relationship and simplifies the process of the numerical analysis.Using this method,an overall analysis is made of the numerical suspension relationship and a relevant conclusion is reached.
