CST MWS在仿真過程中出現(xiàn)這樣的警告some higher order propagating m
some higher order propagating modes at port 1 are not considerded in time domain caculation .this possibly leads to inaccurate energy balance. consider to increase the number of modes or decrease the upper frequency limit,我現(xiàn)在仿真的頻率到11GHZ但看不到截止帶寬,到頻率調(diào)到12GHZ時(shí),就出現(xiàn)上面這種情況,請(qǐng)問高手,這種情況該怎么解決?謝謝!
最后一句不是給提示了嗎?
是啊 如果降低頻率的話,我就看不到截止頻率了,增加模式結(jié)果會(huì)不準(zhǔn)確的吧
為什么增加模式結(jié)果會(huì)不準(zhǔn)確?把原因說出來。
增加了端口模式為3,選擇solve--transient solver parameters ,將mode選為all后運(yùn)行,出現(xiàn)了
hybrid modes exist at inhomogeneous port1 .this could lead to an inaccurate energy balance .
please check your structure.莫非是我天線的結(jié)構(gòu)有問題?
天線頻率范圍?選的波導(dǎo)?
提示說的那么清楚,check structure!
是個(gè)微帶線,天線的頻率范圍在3-11GHZ,調(diào)到3-12GHZ時(shí)就出現(xiàn)上面警告了
減小端口尺寸
en thankyou..
