I actually really like the background music! Its similar to Grants videos. You are using Grants python library for these simulations, correct?

An important point to understand about scattering parameters is that the reflection coefficient looking into port n is not equal to Snn unless all other ports are matched. Similarly, the transmission coefficient from port m to port n is not equal to Snm unless all other ports are matched. -- Pozar

Very well explained and I'm down with the jazz. My only critique is that you used 'reciprocal' several times before actually defining in terms of the symmetry of the S matrix. It would have been better to make that connection before the example.
@OpenEngineeringRF Жыл бұрын
Thanks for the feedback, I think you raised a good point. I tried to keep the mentions of reciprocity as minor comments to expand on what we'd expect to see in the plots, but it might indeed have been a better idea to introduce that section first, as the meaning of 'reciprocity' might not have been obvious to newcomers.

Hi, thanks for the video. At 1:57, why is the voltage divided by 2 to give ai?

Apologies for the late reply - for a more detailed derivation of the power wave equations, I'd refer you to: Kurokawa, K., "Power Waves and the Scattering Matrix", IEEE Trans. Micr. Theory & Tech., Mar. 1965, pp. 194-202 (if you haven't got access, please let me know) As well as the following document: ntrs.nasa.gov/api/citations/20000056853/downloads/20000056853.pdf

Congratulations on a very good instructional video. I will make one comment... At 13:00 you stated that S11 "corresponds" to Return Loss and VSWR, and you expand on the relationship with VSWR but you leave Return Loss hanging. More specifically, the relationship is with |S11|, and Return Loss = -|S11| where both are expressed in dB. The - sign is often omitted, a common error, very common in ham radio. You might consider adding a 'slide' to expand Return Loss (correctly). Well done to all involved.
@OpenEngineeringRF 2 жыл бұрын
Thanks for your comment! You are correct that, strictly speaking, RL = -|S11| (and you can find lots of datasheets and other resources where return loss is 'misleadingly' provided as a negative value, but unfortunately this has become a bit of a convention to some, so I didn't want to introduce a lot of confusion by giving an algebraic relation between the RL and |S11|). This is why 'corresponds to' was used instead of 'is equal to'. The reason I expanded on the relationship between |S11| and VSWR is because it is less obvious how these two quantities are mathematically related. In any case though, perhaps the "Loss (≤ 0 dB)" note may serve as a reminder that it doesn't make sense for return *loss* to be negative. :)
