摘　　要：对波动方程差分解法(WEFD:WaveEquationFiniteDifferenceMethod) 进行了研究,提出了一种新的不共点网格形式的WEFD算法,避免了原算法在导体 表面需要插值处理的缺点。将此方法应用于矩形波导螺钉调配器中,所述方法的计 算结果和有限元法软件(HFSS)计算结果较为一致,说明了该方法的有效性。A novel technique called non-co-point grid wave equation finite difference method was developed on the basis of wave equation finite difference (WEFD) method. The algorithm can avoid the approximate processing of tangent electric field component on a metal boundary. Finally, the screw tuner in rectangular waveguide was analyzed. The computation results accord well with that obtained by finite element software HFSS.
