我是仿真微波諧振腔的S參量用CST2006，不知怎么老出現這個警告，希望大家幫我看看

At least 1 propagating mode at port 2 is not considered in calculation！
1 mode shares the same beta with considered mode(s) -> degeneration
It might be better to increase the number of modes at port 2

下面是我設置的波導端口的參數
Port Mode Type Z-Wave Z-Wave-Sigma Z-Line F-Cutoff
1 1 TE 147 3.74e-014 --- 4.78
----------------------------------------------------------------------------
--------------------------------------------------------------------------------
Port: 2

----------------------------------------------------------------------------
Port Mode Type Z-Wave Z-Wave-Sigma Z-Line F-Cutoff
2 1 TE 147 3.74e-014 --- 4.78

頂一下！沒人看，自己頂一下！沒人看，自己頂一下！沒人看，自己頂一下！
