It's amazing, you can explain expotential series with base of 0.5 if you take students perseverance as an example: TDT01 - 203 394 views, TDT02 - 94 311views, TDT03 - 43 274 views, TDT04 - 20 648 views, TDT05 - 9 040 views.

If you want to do anything in a PhD make sure its out of passion because its tough going and try to assess how it will help your career - whether you see your future in academia or industry. Be very careful, its not about who will accept you but more where is best for you and where you want to be post education. Supervisor "selection" is very important. Others may say different but that's my advice based on my experience with the process :) best of luck to you!
I will say this, at least in the UK RF expertise is a rarity and there is a shortage of talent. If you do a PhD, strive to have a solid understanding of the fundamentals. Again, my two cents :)
You sir, Greg Durgin, are a hero! My professor simply derived all this on our first day of class with no explanation of what all the different variables and constants were. Leaving the entire class just baffled and lost. I now have some ground to stand on and can ask the appropriate questions. God Bless.
So in theory you could tap into the coaxial cable by placing a probe between the center wire and the outer shell.. Cant imagine it would be easy but it should work...
Someone correct me if I am wrong but on 43:05 Greg says that controlling the geometry of the material (coaxial cable) one can design for a target velocity of propagation and a target impedance. I think that is true only for the intrinsic impedance but not for the velocity of propagation. Greg said a little earlier that the geometry cancel out when calculating the velocity. So the only way of design for a target velocity of propagation would be to play with the permitivity and permeability of the dialectric. I am right?
In the lossless case, the propagation speed will only depend on the permittivity and permeability (whereas the relative permeability in a dielectric is approximately equal to one).
I was also asking myself about that two Zs, although asked a bit late and got Dr Durgin a little spooked, i have to thank Bill at 16:33 for asking that question. Aside from that, this lecturer really makes EM very interesting. Thanks and congratulations professor.
I am working with technicians taking the transmission line semester at a local college. I directed them to buy Transient Signals on Transmission Lines and to view all these videos. Superb teaching.
I like the passion . it really shines through and you can tell you love what you do. you are very much in your element. RF was one of my favorite subjects in school.bring on the Smith charts!
Dr. Durgin, frankly, ur likes make that world better, now, transmission lines is like a piece of cake at least for me, thanks and i hope u keep up the good work, many thanks for sharing ur brilliant experience and btw u've a nice presentation skills :)
my lecturer ask me to learn the transmission line by myself, and i find this video! Thx u sir! I really appreciate this video! xD but I have a question, how about the thickness of the transmission line? Is there any influence?
Voltage is a property of an electric field (it is equal to the energy that could be transmitted to a point charge if it would travel from point A to point B in the electric field). Electric fields on the other hand are caused by electric charges. So both things are interconnected.
imagine if you had a female disseminating purely technical information and they interrupted themselves to explain their adventures in greek rush week, or their initial disinterest in an engineering career until their buddy was there, or gave you some unrequested encouragement in the form of promises of how you will someday earn money, imagine the eye rolls
Hello sir, I need your urgent help. Can you please solve a couple of questions of Transmission Lines, for me in which i am facing difficulty? It would be very helpful, Sir. Will really appreciate your help and support. Thanks & Regards, Arpit
I would suggest you to put up your question in the comment section itself so that everybody gets chance to answer. m no pro in transmission lines.but still here it is :)python00078@gmail.com.
python animalia Thank you for your reply. Actually, it's a pdf file (and I can convert it to jpeg, doc, etc.) so cant upload it as a comment. Will email you shortly. Thanks:-)
I wish these guys would state the description for each variable used. Like he shortly explained little z and big z when the student asked. That'll make it much easier for me to understand ehat the equation is telling me about the signal.

I watched these videos during my undergrad and still return to them after a PhD and working as an RF engineer. Simply awesome!
where did you do your bachelors/masters just out of curiosity? I'm soon finishing my undergrad in EE and would like to specialize in RF.

The world needs more professors like this
Man, where were you when I was studying EE?
Thanks!
12:35 can anyone explain intuitively why is there a negative sign?
It represents the direction of the current.
Thanks for sharing your lecture with us! It really help with my self-learning.
does he do the derivations of the equations at 2:46 i dint see it in the first part of the video
he'll do them in future lectures
Thank you so much dear professor. I had a lot of confusions about TL theory. But after watching the video, my understanding is clear I believe.
This is so helpful. Thank you for making these lectures available to the public
So in theory you could tap into the coaxial cable by placing a probe between the center wire and the outer shell.. Cant imagine it would be easy but it should work...
@ 17:32 It is only lossless because he assumes that R = G = 0. Why he does not tell this I don't know.
This man is incredible he makes this class interesting and easy to understand. Quite an outstanding teacher.

I think I'll email my teacher and tell him to act more like this guy
It's so good that you shared those videos with us , which really help me a lot
You can't spell Geek without a double E. 🤣
wish i could go to GT for my graduate school, thanks a lot
Dr.Durgin you have made my Signals Transmission course an enjoyable course. Thank you so much for posting such awesome videos.
i wish i was a Super-Cool 7th-Level Wavemaster like Professor Durgin
The only point I don't like is using z as position variable. That could confuse people with zo (impedance)
I am working with technicians taking the transmission line semester at a local college. I directed them to buy Transient Signals on Transmission Lines and to view all these videos. Superb teaching.
This lesson was explained in easy to understand terms compared to my obtuse class in EMAG 1 at my school.
It seems like there needs to be 1/(2pi) left out in the last formula for microstrip Zo when a>b.
I like the passion . it really shines through and you can tell you love what you do. you are very much in your element. RF was one of my favorite subjects in school.bring on the Smith charts!
Why can't you be my EM teacher ;(
Thank you Dr. D. Wonderful, generous, interesting. raphael santore
Thanks! Doctor. Could you tell us what book you are using?
Of course, (t - z/v) * 2pi . f = (w.t - k.x)
I didn't realize I needed the story at 30:00 until I heard it 😂🙌🏽🕺🏽🔥

but I have a question, how about the thickness of the transmission line? Is there any influence?
Oh how I got lost so quickly. Not your fault, I'm just only 15, guess I better go learn calculus
42:01 and 55:20 Maryland accent!
These lectures are going to save my ass this quarter! Great job!
Greg, is voltage actually charge travelling or is it electric fields?
Voltage is a property of an electric field (it is equal to the energy that could be transmitted to a point charge if it would travel from point A to point B in the electric field). Electric fields on the other hand are caused by electric charges. So both things are interconnected.
Smoke -> Fire, V -> I
awesome lecture sir
Thank you so much.
Thanks, Thanks, Thanks, Thanks, Thanks, Thanks forever 💙💙
You are a hero, thanks from Brazil
Thickness of the medium has effect on amount of current it can carry.
I see so is there any influence with the impedance directly?
Excellent!
Greg Durgin, you are the man.
Lecturer: "Oh it's so beautiful isn't it"
Class: *complete silence*
Where can I find homework questions and answers?
Look here www.propagation.gatech.edu/ECE3025/index.html
38:51 Cough, touch cable with hand you coughed in, pass around the cable. :) Nice lecture so he gets away with it.
and particularly disturbing after going through 2020
16:44 Is that guy in the class?
Dr. Durgin, I love the way you are teaching, Thanks.
Is this for lossless lines?
Thank you!
Is this distributive analysis or lumped?
Listen here: 39:46
this guy is a f%^& beast!
Thanks
u are awesome man

21:41 what material is he talking about I wonder 🤔
