I posted it before, anyone can give a clear answer? thanks
I have some planar samples and designed a free space measurement, I calibrated the rectangular horn antennas THRU-REFLECT than put the sample in the middle of system. The result gives S11 and S21, at some frequencies S11 and/or S21 have/has positive values. Is it correct ? does it have any physical meaning?
Thanks for your valuable helps...
I also have similar problem with coaxial waveguide measurement?
