3.4 Plane Waves

This video was made for a junior electromagnetics course in electrical engineering at Bucknell University, USA. The video is designed to be used as the out-of-the-classroom component and combined with active learning exercises in class. This video covers basics of plane waves, one of the most useful solutions to Maxwell's equations

For the first time after more than ten years of taking the course I finally understand why the term “plane wave”. Thank you so much, you’re awesome!

[jamesdiorio]

Thank heavens for someone who knows how to explain things intuitively, and is willing to record himself doing so.

[condedennisful]

duuuude... you're so much better than my teacher!

[dasilvaleandro]

This is by far the best explanation I have seen. Really clears up how an electromagnetic plane wave looks like in space. It does not look like a rope, but rather more like layered surfaces each one with a constant value (magnitude and direction) of the electric field. Thanks a bunch!

Fantastic video, thank you for making these concepts intuitive. Your teaching in conjunction with the applets makes it very clear.

[ReasonableSwampMonster]

I’ve been trying to get an intuition for this since I learned acoustics 2 years ago and I finally got it thank you bro

[shawnst]

Very helpful. So far the best explanation of plane waves.

[linssendane]

this video is fantastic! taught me a lot. thank you!

[PTNLemay]

Do the electric field lines always point in the same direction as K, or can you have a wave moving through space that are pointing in another (arbitrary) direction?

[rizwanulislam]

Sir does it mean that if one wave travels then it procuces electric field all around the space orthogonal to propagation

[Mulkek]

Awesome video! Thanks, and explain so clearly!

[oussamareda]

thanks for helping me I'm from Morocco it take me time to understand how waves to be plane

[plavix]

thank you so much for your explanation.
Finally a explanation that is sufficient to my needs.
Why dont we have footage in TV! educational aspect of TV is highly unused.

Bro, how do you graph a wavefront in matlab or mathematica?

[abdelrahmangamalmahdy]

Why do we use E & H ? aren't we supposed to use E & B which stand for something physical ?!!! so the intrinsic impedance would then equal the speed of light.

[litiometalico]

How can I define the origin and the vector r. Can I define the origin anywhere? And r any position on space?

[yash]

11:11 dont "circular waves" mean same as circular polarised wave - which is altogether different from the spherical wave shown above??

[nimsarajayasinghe]

what was the book you mentioned at the beginning of the video?

[ProjektKlover]

What's the differens between plane waves and longitudonal waves. Sound waves could also be seen as planes moving forward.

Wow these videos are excellent. Would you be able to recommend a good electromagnetics book? I'm using Elements of Electromagnetics by Sadiku for my class.
