| Abstract: | 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. |
