You just explained better than my professor at the university. I couldn't understand from the books and lectures, but after watching your video, I am just wondering, how it is possible to teach like your video! Thank you man, you made my day!
This video helped me understand plane wave propagation. Thank you so much! Could you please make a video about wave polarization (elliptical, circular etc.)?
@ 00:09 "SUPPOSE WE HAVE TWO LONG WIRES" (with one wire you suggest this is made up of the two lines drawn). @ 01:01 ARE YOU TALKING ABOUT VOLTAGE-DIFFERENCES ALONG THE LINE OR BETWEEN THE TWO LINES??? Advice: Be more clear in the terminology you use!
Thank you for this great effort at simulation and explanation, but there is a small error in the ninth minute 9:11. The direction of the magnetic field inside the magnet must be from south to north(LEFT to RIGHT in the video) and opposite its direction outside the magnet, from north to south. This satisfies Gauss's law, Thus, If we draw a circle at N or S, there must be arrows coming out of the circle. At the same time, Arrows enter the circle
can you do an animation of michelson interferometer measure wavelength. how do the wavelengths interact to make rings to measure the wavelength please.
I have a question, since electricity travels at light speed, we can see difference in the voltage levels after the distance of 3000km, does any transmission has the distance more than 3000km? Please help to understand!!!?
Ok, got an answer to something I wasn't even thinking about. Been wondering why [x^2-y^2-z^2, 2*x*y, 2*x*z]*1/sqrt(x^2+y^2+z^2) is a 3d smith chart. It's that z[l]=(1+Γ)/(1-Γ). There is a rotation function for tangents. tan(pi/4+t/2)=(1+tan(t/2))/(1-tan(t/2)). You're forcing Γ into that tan(t/2) spot. Given, it's not a regular tangent. Maybe it's more of a hyperbolic tangent thing going on.
Oh, shit, I know what all that stuff is. You can't generalize it that way. I tried. When you do the two 'e' exponentials, the sum of the sequence gets messed up. That (-1)^t becomes its own exponential. The helix/drill thing is more cylinder like if you don't do 1:1 (squishing them).
Excellent information! 1988_Cypress_CMOS_Data_Book.pdf (Search “1988 Cypress CMOS Data Book”) is available online . Chapter 10 (starting at 10-60) has an excellent review of transmission line theory. You need to understand complex impedance and basic circuit theory. “Terminate a transmission line in its characteristic impedance.” It is aimed at digital designers, not RF specialists. I realize this is from the days of the IBM PC, but the basics of transmissions lines haven’t changed.
