    CST simulate a free space (2-Port) measurement

    Yes my next step is to simulate the DUT into a perfect waveguide. I think manually is really complicated because of the geometry of the DUT. I was hoping for the existence of algorithms that would do the calibration in post processing, or similar to the macro for material characterization...

    CST simulate a free space (2-Port) measurement

    Ok I understand, so what could I do? If I model my setup to work in far field, how could I implement VNA calibration method?

    CST simulate a free space (2-Port) measurement

    Because I would like to see the influence of my DUT only, as if you were taking a VNA measurement. In a VNA measurement, before you insert DUT you make a calibration and what you see in S12 and S21 is 0dB, I would like to simulate this condition in CST, or to do something similare so that i can...

    CST simulate a free space (2-Port) measurement

    This is what I've done, but the S-parameter are too far from what I expected. There is something wrong with the model i draw but I don't know where is the error. Boundary conditions are open(add space), I set the reference plane to the DUT interface, the background is air (eps =1 mu = 1) and...

    CST simulate a free space (2-Port) measurement

    Hi, I'm new in CST, I would like to know how to setup a simulation to measure reflection(S11 and S22) and trasmission (S12 and S21) with 2 horn antenna and a DUT places in the middle. I have made some measures with VNA but the result doesn't match with the simulation in CST Studio I attach a...
