At this case, if I do individual port excitation, we will not have a power combiner, the input port will be divided in two other ports (power divider).
Thank you very much for your reply.

Thank you BigBoss for your reply
For the power divider we have less -3dB as you say, but for power combiner (two input port1 and port2 ,one output port3) we have s21 and s31 varies between -3 dB and +2 dB, we have problem with power combiner, when we excite two input ports.
Best regards
Big Boss thank you for your reply,
we have already finished our program with the fdtd method, it's part of my project.
yes power comb/div are passives components, but our results of s21 varies between + 2dB and -3 dB
s21 can have a positives and negatives values (between +3 dB an -3 dB)?

Ports are not excited simultaneously by definition of s-parameters
what do you mean about this?
We have excited both ports port1 and port2, they are combined in port 3, the problem is how to extract scattering parameters?
Best regards.
We have used fdtd
configuration
inputs: port1, port2
output: port3
RT 5880
I want to know if it's right or wrong: for the calculation of s21, the two ports port1 and port2 will be excited at the same time by two excitations and we calculate the fields?
Dear all
Hi,
I have simulated a two way power combiner, two inputs port1 and port 2 are excited by two excitations with the same amplitude and combined in outport port3, but the resuts of s21 and s31 hqve a positive values (+ 2dB).
My question is, can have a positive values for s21 and s31...
