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 in dB?
I check several times my promgram, I do not know where is the problem.
I have used the fdtd method for simulation.
i have extract s21 by a ratio of the incident waveform at port 1 and the transmitted waveform at port 2 ( Fourier transforms).
i will be very grateful for your help and advice.
Best regards
