I've been looking for a good explanation on impedance matching cause I never really got it in my fields course. This video has amazing visualizations and explanations. Thank you so much
Great 4-D video showing the often ignored time and especially the imaginary part! Someone already pointed out the wrong highlighted negative sign by Gamma. The voltage/current amplitude triangular chart also is slightly wrong. Gamma is the same for both voltage and current (there should only be one circle for showing 1 + Gamma and 1 - Gamma), but the voltage/current amplitudes have different prefactors (by a factor of z_0) which scale the whole term in parentheses. If just showing 1 +/- Gamma, there is one circle and a clear way to see the standing wave ratio.
I think there's a mistake at @8:45. That minus sign is the same for both current and voltage. I think it's the sign in front of Gamma which rotates the vector 180 degrees.
Yes! This is AWESOME information! Ham radio operator and HUGE interest in radio here. This is the best explanation I have ever seen of this. I learned so much seeing this video! Thank you! Subbed and belled!
Giving some practical examples using capacitors or ... would make this video more understandable for other students with different background who are interested in this topic.
I have to deal with real world transmission lines. However, my transmission line is much shorter than the wavelength of my generator signal (it is in the kHz range). I just cannot comprehend how standing waves will form in it. Do we need more complicated math for this case? Does your visual explanation still apply analogously?
I think the answer is in the first video of my transmission lines playlist. notice that the standing wave pattern repeats each half wavelength of the signal. So if the wavelength is too large compared to the line, there's no standing wave and you can treat the line as a simple wire in circuit theory (super conductive wire with infinitely small dimensions). as a rule of thumb you can use the lumped element model if the line is less than (1/20)*wavelength. Hope that help
Certainly excellent job done on this video, this kind of video is good for VERY intelligent poeple? but I think that not every one could understand, personnaly I did not understang it all, specialy 3D diagrams. The simplier the better
Bro do know u alternating current, electric field and capacitance on long transmission line? If u dont know check out him video about transmission line
8:42 is that the right minus sign? Or is it the one to the left of the gamma that represents a phase shift by 180°?
yes! you are right
thank you
you sir are amazing , a half semester of my professor trying to explain this and you swept every thing in 15 minutes. Brilliant!
What are you studying where they cover this?

One of the best videos I have seen about transmission lines. My congratulations!
there's a mistake at 7:48. the exponent for the common equations should be +2*beta*l, not negative
3D visualization of these theories is so rare and you're doing a great job sir. Thank you for your videos.

Yes, You are right :)
This channel is pure gold. Would love to hear more about power electronics or energy engineering from you :) ❤
Wowwwww! Very excellent video!!!
Beautiful animations, clear exposition, enlightening concept. Great job and thank you for your hard work! ❤

The graphs in these videos are awesome. I love it!
Brilliant explanation and animations are great as always..

from an electronic engineer perspective this is absolute genious
The world's best teacher thanks sir
These animations are perfect! Thank you for a new video
Please continue this playlist.
Awesome Sir with 3D 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍🥲👍👍👍
Great work man. appreciated!
Good Job! Outstanding educational content!
Fantastic animations
This video is amazing
Meraviglioso. Cheers from italy!
Great video. Thank you
Your content is amazing!!
Please also do a video for waveguide propagation too.

I love thinking about math in the context of physics, it really helps
You have a new top fan!
Do you have a patreon?
Yup
I LOVE THIS
Thank you very much.
Thank you
Excellent video. Which program do you use for the animations?
please read the description
@@TheSiGuyEN thank you so much! I tried to check the code on git hub link on the description but it says error cannot be found the git repo
Brilliant! Thank you
YOU BRILLIANT!!!
why at 7:16 you say that the current is 180° out of phase if in the graph on the top left corner they are out of phase of 90°
Grazie! ❤️
Just a dumb question - why we took I is 180 deg shifted from V
Brilliant!

look at this from 2:50 to 4:30

and this from 00:00 to 0:45
Where have you gone a decade ago 😫
Admin, do u have code for this video?
It's aligned in a flux then condensed into a conduit.
amazing
Why did you stop posting mate. ❤❤❤
Wouldn't the power company use a capacitor/inductor to fix the signal coming back so that the impedance of the reflected signal is purely real?
There is virtual no way you to get rid of the characteristic impedance of a transmission line.
Maybe
Where’s the attenuation constant?
so far in this playlist we assume lossless lines. I think it would be better to include losses in a separate video.

Voltage does not propagate. It is the measured potential difference between two points. Neither current propagates. It flows. Waves propagate.
Bro do know u alternating current, electric field and capacitance on long transmission line? If u dont know check out him video about transmission line
Did u think this direct current?
My professor is cool but god damn I cannot follow him or read his cursive handwritten slides
Please also do a video for waveguide propagation too.
