extremely helpful and informing content, thanks☺

Awesome. Quick and to the point. Thank you!

Hello! It is a really great video thanks for sharing but I want to ask you about S23 and S32 these values are equal to each other and its value is 0. I saw this in another channel and I got confused about it. If these are equal with by mines only? 14:43

very nice!!!

Its the best video available on this concept.

this is great thank you! what happens if it's PMC and NOT PEC ??

Sir I have a doubt, if signal is travelling from port 1 to port 2,port 3 and it is -3db . If signal travel from port 2 and 3 then it should add the signal and it should be 0 db

Best explanation of the Smith Chart !!!

Wow. What a valuable scientific information. It's like put light on darkness.

Also, what is not stated is that it is vital to properly calibrate the NVA before the measurement!

Nice explanations and derivation of the required formulae. However, in my understanding there is one main flaw which is pretty fundamental: It is stated that the inductance (L') varies with frequency because of the skin-effect. This is correct, however, the phase velocity which is used instead is also frequency specific and not frequency independent! Also, the measured capacitance for a cable also varies with frequency, so the same reason why L' cannot be measured directly (and used to compute Z0) could be applied to C' as well. So the reason why the example measurement turns out to be pretty good is that the lambda-quarter frequency was found at 33 MHz which is a reasonable frequency to measure this cable. I did a quick comparison (with my LiteVNA) between the proposed measuring technique from the video and simply measuring L' and C' directly (at frequencies between 1 - 200 MHz) and found that the error is about the same with both approaches.

What is the name of your book? where I can find it.

Hello, you sure about ISOLN, what is the logic behind that? Because oficial tutorial says that "If there is only one load, connect the LOAD standard to port1( CH0 ) , the port2( CH1 ) can be left unconnected."

Can you please share what that book is ? it does not seem the book you mentioned by Clayton Paul

This is the best NanoVNA tutorial on TH-cam. Thanks and bravo!

Thank you from Canada!🇨🇦

Wow, thanks to the TH-cam algorithm and thank you very much for this amazing explanation.

Great work 👏👍👏 thank you

life saver <3

Thanks for all the videos!

What book was that?

I cannot thank you enough. You explain so perfectly, that there is never a moment that i cannot follow. Everything makes sense

Should you be doing this with your coax coiled in a tight loop?

Hey mister James Nagel I wanted to thank you for your courses it helped me very much. Is there a Microwave engineering II course available ?

Thank you. This is very helpful.

Awesome! Just had a chance watching this 3 year old video. Could someone explain why Vp=0.67c?

@ 2:16 This substitution is done to get rid of the quantity dI and obtain a relation between V's only; the same for the I's, of course.

@ 8:49 What is so steady about the SSS?

@ 3:51 Unfortunately, this is NOT what's happening physically: because only negative charges (= free electrons) are moved by the potential difference. But the result is the same.

thanks!

thank you

Helpful ❤

Great video. Thank you!

Hello!

Great explanation! Thanks a lot

This is great and helpful

Very nice explanation, thak you sir. The Kernal in Fredholms equation is actually the Green's function if im not mistaken. This shows somehow the power of this method. If i know the Green's function i can apply this method to solve many different type of Problems.

Greatly Imspired. Finding Helpful.

What is comformal mapping?

Page 81 13. S. B. Cohn, "Problems in Strip Transmission Lines," IRE Trans. Microwave Theory Tech., Vol. MTT-2, pp. 52-55, July 1954.

Such a wonderful explanation, you're the best!

Thank you so much for making this video. Excellent explanation 😃.

What was the logic for performing the derivative of the equations with respect to Z? I know it generated the Helmholtz equation but I’m trying to conceptually understand why it was performed.

Great explanation! Thank you so much!

In the simulation can you define the axis please ?? Thanks for the video series explaining wave modes from the beginning !!!

The best explanation I've seen how to understand why it is used 50 Ohm impedance cable. Thank you very much.

Hello Sir, For E(x,y,z) = E0*e^-j(ky*y + kz*z) in x axis, travel direction in z direction. Is it true that, if ky is not 0, then it is TE mode, if ky is 0, then it is TEM mode?

Can you get the transmission coefficient without using the matrix, such as voltage division?
