Electromagnetic Boundary Conditions Explained

[@ozzyfromspace]

You explained it to me like I was a little kid, and you know what? I’m not mad. Your explanation is EASILY THE BEST one on KZbin, and trust me, I’ve been around many a channel. Thank you for prioritizing clarity over fancy talk. You’re a real one, Jordan. Best wishes with your channel 😊🙌🏽🎊✨

My EM II prof said I shouldn't try to attempt to visualize EM, but this is exactly what I needed. Thank you!

[@user-jm6gp2qc8x]

Wth

[@thoughtful2096]

Sounds like a shit professor. My em professor was pretty similar. He spent more class time boasting about his research than actually teaching the subject

[@cashcolby8299]

InstaBlaster.

[@Godakuri]

@@thoughtful2096 Holy shit, my E&M professor was the same damn way. Im relearning E&M by myself this time with Griffiths

[@PedroTricking]

Isnt EM one of the most visualizable areas?

[@EigenA]

Great work, I wish more people would adopt your clear and concise teaching method.

[@brandyngabel5148]

Thank you!! My EM teacher sucks, and the class is super hard. The material is actually easy to understand when it's explained well like this.

[@michaeljburt]

I'm an EE and been reviewing some of your videos on the Fresnel equations, characteristic impedance, etc. Boy do I wish I had these during my undergrad E. Mag. courses ... haha. Thanks for the great content, really brilliantly explained

[@quasar7312]

I was stuck with this concept for the last two weeks. I tried to visualize it, worked on it but couldn't actually get to the point where I could actually understand this. But now I can safely say I have grasped the concept of boundary condition. Thank you so much for the video.

[@Rahul.001]

I would have never understand this if it wasn't taught in this way. This is the simplest way one can teach the concept of boundary condition.

[@SadyaMartínez]

You really made me fall in love more with my career. Thank you, you remainded me why this is worth it!! Have a great day.

[@aldojuarez1278]

Thank you! I struggled with the concept for a week, I finally got it

[@donutzzs]

best explanation after an hour long search

[@memsuniverse]

This is really good point, I always had hard time to understand the BC (boundary conditions), thank you for the great explanation also

[@chrissysevigny2462]

This was really helpful, and felt a lot more intuitive for me, thank you so much for posting!

[@leonidastsigounakis5796]

I’m currently doing my second year as a EEE student at imperial college london. I appreciate the effort put in these videos. Great Work! :)

[@JordanEdmundsEECS]

Greetings from across the pond! Thank you :) If you have suggestions to improve them, I am all ears.

[@sharada_dance]

I am learning much more from you than from my university professors! thank you thank you!

[@agustin19]

Incredibly, I understood in this video (in a different language than mine), a few hours of reading in books that I don't quite understand. Thank you

[@xenusonofzarnox]

great grat explanation, simple, clean, thank you.

[@pra601]

watched several videos, this has to be best video ! Great work and wonderful explanation.

[@Mohk610]

This is amazingly well explained

[@mahmoudelgeziry5160]

Thanks Jordan, this was very helpful.

[@amirjodeiry7136]

extremely appreciate of your excellent explanation....... It was very helpful for me. Thanks a lot .

[@gauravmishra-oi7nw]

Thank you for this excellent visualization and explaining the boundary condition. I have a question regarding the direction of electric field vectors in material and vacuum side. To make a loop, the tangential component of electric field vectors in material and vacuum side may be pointed in opposite direction.

[@brahamjeet602]

excellent explanation sir

[@NerdKing9826]

Best explanation I have seen. Many thanks!

[@edilturdumambetov389]

Hi Jordan! Thanks for the quality video.

[@JordanEdmundsEECS]

:)

[@filipstanisic7139]

You are making such great Videos. Thank you so much for making them.

[@roliomurao14]

Great explainer ✅

[@quocanh2901]

thank you sir, u save my life

[@danielribastandeitnik9550]

Good video, but I think it is missing an important detail to the argument that made me spend some hours thinking haha. When you say that the parallel (tangencial as you call it) components of the fields are equal, it got me a little confused because given a 2D plane (since the boundary is a plane, not a line), you need to define a specific unit vector parallel to the plane and only so can you define a specific parallel component of a vector. If you don't do this, there is an infinite possible 'tangencial component vectors' since you can rotate the trajectory you have draw. What I think is missing is to start saying that, given the two electric-field vectors on both side, one can always find a plane that contains both fields. So if you make this plane parallel to the screen (to the paper you are drawing), then you can continue with the arguments you presented and end concluding that the parallel components that are defined as (a) parallel to the boundary and (b) contained in the common plane to both vectors must be equal. If you want to go one step further, you can say too that n x (E_1 - E_2) = 0, where n is the normal vector to the boundary and 'x' is the cross-product. In the light of what I wrote and a little thinking leads to this conclusion which is a nice geometrical relation.

[@Akshay-xo5iy]

Sir, you are the best!!

[@blzKrg]

This is extremely helpful!❤

[@murtaza-magsi]

The line integral of E equals zero (0). Doesn't that means that when you kind of sum/accumulate the E vectors on the loop they cancel each other out. So that the E field drawn in red should be negative to the white E field (i.e. oriented in opposite direction).

[@Shubz93]

how will we do this for circular waveguide with half of it being filled with dielectric and half wih air?

[@sfisfun]

Is this anythings related to discontinuity equation

[@andyralph9495]

At 4:19.you have shown Electric field lines to be parallel but they are radial....is this because you are considering an infinitesimally small area?

[@MS-oy4vo]

Sweet video bro. I wish KZbin would put the "next" video in the "up next" section...

[@JordanEdmundsEECS]

Me too, eventually I’ll figure out how to add in those in the end credits.

[@henrymiller5709]

clear and simple, thx

[@sarujanrupan4831]

Why is E and H used as opposed to D and H or E and B.

[@raginibhayana8305]

good explanation I really respect you sir thank you so much sir

[@reemalshanbari]

If the interface between two material along x,, which components of the field would be continuous? like in Ex or Ey or Ez? if it is TE polarization?

[@duongnphong]

hello, i am doing a report, I have a question, does it apply for antenna study?

[@JordanEdmundsEECS]

Yup! Usually antennas are made out of metals and so the electric field inside them is zero (or very nearly zero) everywhere.

[@davidwillian2279]

Great explanation!

[@lencanotes]

Will you be continuing to add to the emag playlist?

[@JordanEdmundsEECS]

Yes! Very shortly I will be adding to it.

[@puregeophysicist7448]

Can you please tell me the name of App you explain on ?

[@JordanEdmundsEECS]

[@angelsasikala4792]

Need more clarity on boundary ...don't assume ..just prove it...
