HFSS端口激勵(lì)怎么加

不知道在加激勵(lì)源時(shí)有哪些總體的，一般的考慮，是加lumped port還是wave port總是搞不清楚；還有在driven modal和driven terminal兩種求解下還不同；積分線又是怎么回事？
希望高手多指點(diǎn)，還有，版內(nèi)有沒有什么好資料推薦下。

With lump port=> the excitation is applied at a point/cell, as a voltage or current. 本文轉(zhuǎn)自微波仿真論壇
lump port的激勵(lì)以電壓或電流的形式，加在一個(gè)點(diǎn)或單元上。
With wave-port=> the excitation is so-called eigen-wave, such as the quasi-tem wave supported by a microstrip line. It applies over a cross-sectional area.
而wave-port的激勵(lì)稱做本征波，比如微帶線饋源提供的準(zhǔn)TEM波，它加在一個(gè)橫截面（剖面）上。
voltage is scalar, wave is vector by nature, hence there are substantial difference between the two. So use waveport whenever possible, because "simulation of wave phenomenon" is what HFSS is designed for. And compare with the "correct" measurement whenever possible (i.e. measure "wave", not simply "voltage").
電壓是標(biāo)量，而波本質(zhì)上是矢量，因此兩者間有很大區(qū)別。當(dāng)情況允許時(shí)，盡可能選擇waveport，這是由于HFSS是為“波仿真”設(shè)計(jì)的，相對(duì)于簡(jiǎn)單的“電壓”，測(cè)量“波”可使結(jié)果更精確。
Why lumped port is there? It is easy to applied and people found that good/reasonable results can be obtained. Why? if the frequency is low enough or the excitation is applied at sufficiently small area, then the "wave" can be described by some "voltage" or "current", which must be "measured"/"calculated"/de-embedded/etc in the correct manner.
那為什么還要使用lumped port呢，這是由于lumped port激勵(lì)的添加簡(jiǎn)單，并且可獲得良好的結(jié)果。如果頻率很低或者激勵(lì)加在足夠小的區(qū)域上，“波”就可以用“電壓”或“電流”來描述，必須用正確地方式測(cè)量、計(jì)算。
if the excitation can be applied on some locally uniform region=>waveport,
if geometry/material discontinuities are near/closer to the point of excitation=>lumped port might be the only way.
另外，如果激勵(lì)可以加在某些局部均勻分布的區(qū)域，應(yīng)該采用waveport，如果激勵(lì)點(diǎn)附近存在幾何或材料上的不連續(xù)區(qū)，lumped port可能就是唯一選擇了。

這是以前別人的回復(fù),希望能對(duì)樓主有幫助.

full book上有很詳細(xì)的介紹,可以看看.

full book我看了幾遍，還是不太明白，遇到具體問題不是很清楚。而且10和11說法還不一樣，關(guān)于積分線，終端線，很是苦惱。
