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?

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?

Love you. Marry me please. You explain things so clearly 😩😭

very engaging coment

Tnx !

You are one great instructor!!!👌👏 I understand everything you teach!!!

Thank you

This video was helpful to tie the phasor math back to real signals in the time domain. Around 6:51 in the video you write ...- j*sin(...). Where did the negative sign on the j*sin term come from?

Intersting to see that reflection cause current and voltage lag, so the source sees a reactive load, and VSWR is also well visualized

very good!!!!!

Thank you for this vedio this vedio was very helpful for me.From Egypt

So... in coaxial cable TEM is just "normal" electric circuit behavior and that's why it has no cutoff frequency? Despite coax's (or parallel plate's) gap size being centimeters it can pass 100 meter wavelength RF signals because the waves don't actually have to fit in the gap. They're from charges moving in conductors. And the TE/TM modes are very different mechanisms entirely where the space between the conductive cavities has to be big enough to support the electrical length of the frequency's TE or TM mode electromagnetic wave propagation? So tiny diameter coax in TEM mode can pass DC to some high GHz, it's actual size doesn't matter because it's just wires being wires (even if impedance is defined by the ratio of radii). But with a the TE_11 mode in a too big for the frequency coaxial cable, the absolute size *does* matter. And no centimeter size coaxial cable can pass a 100 meter size TE_11 mode wave (efficiently). But a giant 50 meter coaxial cable of the same impedance could.

in u another video u said V0 is a complex number..

Thanks a lot professor! Your lectures helped me a lot for my university exams.

I stumbled upon this lecture series (KZfaq suggestion), while trying to do a refresher on electromagnetic theory via another lecture series which started with transmission line theory. What a beautiful description ❤. Thank you, Professer James Nagel🙏 And long live KZfaq!

Just re-ran across your channel again and would like to attempt your course. 😊 Anyway, KZfaq suppresses all the good channels so they can make the most ad revenue 😢 So, thanks for making all this great content 🤓 73…

Thank you and will look into your other videos! 73… 😊

At 2:19 you placet surrogate load Zl1' (backpropagated Zload) behind Z1 section. Why you didn't do that in front of the Z1 section?
