3.6 Plane Waves in Matter

[@Ezequiel_Anibal]

Your videos are extremely good and intuitive!!! Thanks sr.. I'm 21 years old, I'll save those videos for when I get a son !! Lol

you got a son yet? :)

Hi, man, have you got a son yet, hhhh :)

Eastern World 😂😂😂😂😂not yet. I don’t even remember I posted this.

Dear Kridnix, Hi. If you try to plot the slide at 14:05 in your video in MatLab, you do: fA = []; for i = 1:n_media alpha = media(i, 1); betha = media(i, 2); %4*pi z = z_media(i, :); %plane-wave equation assumming epsilon_complex fieldAmplitude = E_zero*(exp(-1*alpha*z).*exp(complex(0, (w*t - betha*z)))); fA_temp = real(fieldAmplitude).^2 - imag(fieldAmplitude).^2; fA = [fA, fA_temp]; end However, I am not able to reproduce your curves using the given values of alpha and betha. Are you multiplying them by a factor somewhere? Thanks for your answer :) It will be extremely helpful.

in 7:54, there is a mistake. if k=a +jb then E=E0*exp(bz)*exp(j(wt-az) , no?

[@Shiny_Mewtwo]

8:42 It may be j(a+jB)

[@ellahammaslamma]

I think that the expressions for alpha and beta are missing a factor of omega on the outside of both expressions...

excellent sir..............

simply brilliant ..

[@leonardoferreira7960]

omg... congratulations for the video.

Hey man, I used your videos as the basis for a project I did in my PDE's course on the 3-D wave equation, so thank you for posting such an in-depth analysis. One thing I wish I could have done though was shown your simplified model for the plane wave with chosen values of alpha and beta (I ended up drawing them by hand). Is there anyway you could upload those/provide a link where I could view them outside of your youtube video? Thanks!

Hi what book are you referring to?

thanks...
