我是仿真微波谐振腔的S参量用CST2006，不知怎么老出现这个警告，希望大家帮我看看

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

下面是我设置的波导端口的参数
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

顶一下！没人看，自己顶一下！没人看，自己顶一下！没人看，自己顶一下！
