摘要
为了探讨将Diakoptics算法应用到开放式微波结构时适宜的时域模函数形式 ,在对槽线、共面波导、微带线及耦合微带线的空间电磁场分布特性分析的基础上 ,提出零阶、一阶第一类贝塞尔函数是较适宜的时域模函数 ,并总结了选取规律 .
It is very important to choose proper time domain modes when microwave structures are analyzed by time domain Diakoptics. Efforts were made to find out the proper time domain modes for analyzing open microwave structures. Based on analysis of electromagnetic field distributions for such open microwave structures as conductor-backed slotline, conductor-backed coplanar waveguide, microstrip line and coplanar strips, the zero and one order Bessel functions were proved to be the proper time domain mode functions. The rules of choosing time domain modes for these open microwave structures were summarized. The results can provide useful references for further investigations in this field.
