Origin of TE and TM Modes

[@noahballou6350]

Are you planning on becoming a professor? We need you in the classrooms, you are exceptionally good at explaining fundamentals and that is a rare talent in the school system

[@zb5775]

So true! He did more with a few short videos than my EM prof, in 3rd year EE, did in the whole semester.

[@zhengyangg4708]

5:35 I believe there's a typo on your lecture slides. For the reflected Kx it should be Kx = Ko*sin(θ). Just for the future viewers. Great video as always!

[@giorgosgagrinas9365]

Yeap that it is probably right! Just commenting for anyone wondering if you are right.

[@alejandroromero6464]

True.

[@VectorTutors]

Thanks dude

[@abuabdullah9878]

thank you

[@LightHolmes]

Man, your videos helped clear up a ton of things. Can't thank you enough.

[@amartanshdubey9750]

Great explanation! You should also make a video showing how waves will propagate inside the rectangular waveguide.

[@tylergeneharrison3594]

Electromagnetic just got fun! Best explanation I believe I have seen!

[@aJ-sk2hf]

Please make a follow up of this video. Great explanation!!

[@christianmierescurra6392]

Hello Jordan, great job. I couldn't find the continuation video about TE and TM modes, if there is one. Thanks.

[@bharathchoudhary3185]

Great Quality Explanation With Details!!

[@pyrokinetikrlz]

Goddammit! That was a great explanation of TE and TM waves!

[@JordanEdmundsEECS]

Thanks! :D This video came out of a conversation I had with another grad student at Berkeley, Cem, he's awesome. It makes so much more sense to me this way.

[@aydogakallem6450]

Thank you for this simple and clear explanation!

[@PTNLemay]

8:40 I find the terminology a bit confusing, because if we ask ourselves "Ok, in TE mode how are the magnetic waves propagating?" We would find them to be at right angles to the electric component and at right angles to the direction of propagation. In our volume here they would oscillate in the Z direction. This is also transverse to the direction of propagation (which I understand to be in the X direction here). I get that it's just a terminology that the industry agreed upon. But would it be false to say "In TE mode the magnetic field is also travelling transverse to the direction of propagation"?

[@JordanEdmundsEECS]

Uh, usually these modes are confined inside a waveguide, so they aren't *really* traveling at all, they are sort of stuck. In free space, this might be more correct to say.

[@KaptainLuis]

omg this helps sooooo much! LOVE YOU! Thank you veeery much!!!

[@JordanEdmundsEECS]

[@حسن-د7ص6ت]

How can i determine the waveguide when be TM or TE

[@Cb12500]

If the electric or magnetic field components from the TE and TM mode goes to zero will the wave be still an EM wave?

[@JordanEdmundsEECS]

Nope. A magnetic field cannot exist without an electric field if the wave is to propagate.

[@albo5194]

@@JordanEdmundsEECS So the magnetic field does then propagate in wave direction in a TE mode right? But doesnt the poynting vektor of the wave always have to be orthogonal to both electric and magnetic field?

[@samarfawzy7240]

is it correct to say that s-polarized light will not give a TM mode? because the E field must be in the plane of incidence for the H field to be pointing at us? so it has to be p-polarized light?

[@memsuniverse]

Great explanation , many thanks

[@satyamdas151]

Love the way u explained all...

[@mutazshannag2353]

Amazing explanation thanks a lot for your great efforts.

[@JorgeMiraUSC]

Great job, congratulations! What program do you use for this? I specially find useful the possibility of shifting the blackboard without deleting the previous writter work. Thanks!

[@JordanEdmundsEECS]

Autodesk sketchbook, yeah I love infinite canvases.

[@kevinyao7468]

Shouldn't there be an additional term in the reflection to account for the 180 phase shift, if we are talking about microwave waveguide here?

[@JordanEdmundsEECS]

Sure, if it’s a metal.

[@kevinyao7468]

Since the 2 cos terms are multiplied with each other, in stead of addition, maybe it's better to say it's it's a mix of standing and traveling mode?

[@JordanEdmundsEECS]

I’m confused as to why they multiply. You’re adding two waves on top of each other, and using linearity of Maxwell’s equations. You’re correct that there will both be a standing wave and a traveling wave :)p

[@ayeleleka4976]

thanks for your explanations,

[@GurITheGurU]

Simply Amazing , Love your work , waiting for more on TM & TE modes. Are you planning a follow up , I am kinna stuck at TM mode analysis. 😅

[@billfang3664]

Great Video! Could you make more video related to waveguide and finding attenuation

[@Masongao]

very clear

[@niklaskras5498]

good video!

[@kanishkakosala9078]

Great!! Thanks man..

[@aloysiocamposdapaz8041]

you are amazing

[@phy_dude]

Decent content

[@isaacjohnson4123]

Absolute clickbait. You didn't explain the figures in the thumbnail.

Very good explanation, thank you 🙏
