摘要 文章用有限差分法(FDM)分别结合假想边界和远边界计算开放式微带线的特性阻抗,并对两种计算结果进行比较,证明用假想边界的方法来计算开区场问题是正确而有效的。作为应用,计算了微带尺寸比例及介质基底参数变化时微带线特性阻抗的变化情况。 This paper describes the application of far boundary method and fictitious boundary method combined with finite difference method to obtain the impedance of unshielded microstrip line, and the comparison of two results is presented to validate the accuracy and efficiency of the fictitious boundary method.
