The results showed that MWI in cylindrical coordinates can be used to accurately calculate the numerical reflection error caused by different mesh increments in non uniform FDTD.

计算结果证明，当采用非均匀圆柱坐标系下FDTD法计算时，圆柱坐标系下网格波阻抗可以较准确地计算由于网格尺寸不同造成的数值反射误差。

These principles were the result of thousands of years of reflection on periods of trial and error by the greatest minds of each of their times.
