摘　　要：本文用时域有限差分(FDTD)法计算了矩形波导中E面膜片的等效参量.为了很好地吸收波导中的散射波,采用了一种高精度的稳定的色散边界条件来截断计算空间.在考虑膜片厚度时.本文用环路积分法建立起膜片附近的修正迭代格式.所得结果与文献中的结果吻合.In this paper, the equivalent circuit parameters of the E-plane strip in rectangular waveguides are calculated with the finite-difference time-domain (FDTD ) method. To absorb the scattered wave adequately, a high accurate stable dispersive boundary condition is used. The corrected iterative equations for the nodes near the strip with finite thickness are developed by the Contour Path method. The results agree well with those which in the references.
