Single-Ended Waveguide Ports in CST MWS
虛心請教
不知是否有人使用過Single-Ended Waveguide Ports in CST?
問題:
如標(biāo)題 如圖
如HELP文件:
Above a two-conductor microstrip line is shown as an example. The two upper pictures visualize the two physical QTEM modes that exists on the line: the even and the odd mode. These two modes are excited during the simulation and consequently the solver produces S-parameters corresponding to these modes.
Now, a postprocessing step is started which recombines the S-parameters due to thegiven voltage/current representation as depicted in the second row. Thus, the new S-parameters represent the behavior of the two separate conductor lines, enabling e.g. the analysis of crosstalk between them.
Now it is possible to recombine these somehow basic S-parameter resultsin CST DESIGN STUDIO™ to common or differential formulation as shown in the last two pictures. For this example the new S-parameters equal again those of the even/odd mode simulation.
setp1:QTEM 使用 mutipin port 實現(xiàn) (1+,2+)(1-,2+)
setp2:在後處裡的部分應(yīng)該如何去給voltage/current ?

樓主問題描述得不夠清楚。你是不是已經(jīng)用Multipin Waveguide Port設(shè)置了兩個Definition Set,并且已經(jīng)得到了differential mode和common mode的S參數(shù),現(xiàn)在想通過postprocessing得到single-ended的S參數(shù)?
幫助文件中所說的"given voltage/current"你不用操心,Design Studio中的mode conversion module會替你做這個分析的。你只需要按照那個application note后面給出的連接示意圖連接就可以了。
先謝謝EDATOP 大
我是想通過postprocessing得到single-ended的S參數(shù).
Design Studio中的mode conversion module會替你做這個分析的。
我的CST 版本2008Design Studio 是否沒有mode conversion module??還是??
希望不是版本問題'
我也有作差分元件,也許我們可以交流一下。我看不見你的圖,你能告訴我這段help文檔的具體出處嗎?我可以對比一下我這里的。

Single-Ended Waveguide Ports
2008版我不清楚,Mode Converter元件在Miscellaneous -> Ideal里面。
你的意思是用multipin port設(shè)置even和odd mode,得到differential mode和common mode的S參數(shù),然后再通過postprocessing 得到single-ended 的S參數(shù),然后再導(dǎo)入DS中加入Mode Conversion Module,得到differential mode 和common mode 的S參數(shù)嗎?那這樣做不是多次一舉嗎,直接在MWS里面用multipin port不就可以直接得到differential mode 和common mode的S參數(shù)嗎?
我的回復(fù)在于詢問樓主模型的細(xì)節(jié),因為我看不出來樓主是如何處理他的模型的。
按照幫助文件的描述,這個操作是用single-ended waveguide port得到single-ended參數(shù),如果操作者需要的話,在DS中可以再處理為differential mode和/或common mode。
麻煩問下前面有沒有做過用single-ended仿真得到的S參數(shù)與用multipin port仿真的differential and common mode的S參數(shù)轉(zhuǎn)換的單端S參數(shù)進行比較過?。?br />
這樣的沒比過。
