| 摘 要： | 椭圆波导和椭圆同轴传输线在实际中呈现出越来越重要的意义，而对它们的传输特性理论分析却比较薄弱，本文采用当代流行的数值长法－0－时域有限差分法（FDTD法）计算和分析了椭圆波导及椭圆同轴传输线的截止波长，并给出场分布，该方法可推广用于计算椭圆微带屏蔽传输线的传输特性。

| Abstract: | In electronic transmission application, more and more importance has been attached to the elliptic waveguide and the elliptic transmission line. In this paper, an FDTD method in the elliptic coordinate is proposed to calculate the cut_off frequencies of the elliptic waveguide and the elliptic transmission line. And the field distribution is also given. This method can also be used for analysis of elliptic microshield transmission lines. |
