I am trying to improve the example model with 2 output ports to calculate S parameter for single port.
But the S parameters look so weird, S21 is 0.51. S31 is 0.77. The transmission power from 2 ports is higher than input.
The original model is from
MMI_simple.lms (413.2 KB)
Could you please help me to modify my model?
Thank you very much!
