Hello,
I’m a professor of Electrical Engineering at the University of Quebec in Canada. On this channel, I present our latest research on both theoretical and applied electromagnetism. You’ll find detailed explanations of the Finite Difference Time Domain (FDTD) method, a powerful numerical technique for solving Maxwell’s equations in the time domain.
Additionally, I offer courses on digital communications, RF technologies, and electronics, some of which are in French. You can also explore videos created by our undergraduate students, showcasing their diverse projects in electronics and computer science.
I’ll be discussing various topics related to the theory of relativity, including its historical development, critiques, and alternative perspectives. Another playlist will delve into quantum phenomena that we’ve recently been able to replicate using classical electromagnetism.

Wow! I’m already blown away by seeing Maxwell brought to life! Looking forward to digging into this!
Thank you very much for your support. I plan using less AI for the other parts.
Nice video! Great work!
@@SapiensSpectrum1 Thank you very much for your support!
I love your comprehensive analysis.
How many hours does it usually take to run these codes?
@@imk820 Good question. Using our server without GPU, one simulation required 48 hours. I hope to buy a good GPU to simulate more complex problems and reduce computational time.
Supeeeeer 👍🏻
👍🏻👍🏻👍🏻
how freq(in your case its 2.4ghz) is related to dimensions?
You can see in the video, some length are expressed in terms of wavelength. Changing the frequency changes the wavelength and thus the physical lengths in mm.
Hi great video. What formula's did you use to pick the dimensions of your antenna based on the desired frequency range?
@@NathanMcDowell-pt8hi Please check in Antenna Engineering Handbook, by Volakis. Best regards
Hello professor, can you show how to do this step by step
@@tranminhuc3013 Ok, let me think how to make the tutorial on this
Great job 👏🏻👍🏻
Thanks for the visit
It's amazing that you can simulate those things with in-house codes. Could you give some lectures about the "coding" part of the FDTD? How to set arrays, implement, and so on.
Good idea, we will do it. Thank you very much.
@@profhalimboutayebthank you so much professor!

According to Arthur Miller book - Albert Einstein's special theory of relativity - Galilean transformations were not named until 1911. Abraham Pais gives different date of 1908. But the point is - Lorentz transformations came before Galilean transformations. Calling them Galilean transformations gives the false impression that they came from Galileo before Einstein's relativity. But fact is - it was Einstein's relativity first in 1905 followed by Galilean relativity a few years later. (Calling it Galilean relativity is thus a misnomer - it wasn't anything that Galileo dealt with.) I also pick up on what Miller says about Einstein being mistranslated into English. My Einstein mistranslated video at - ruclips.net/video/eCfzuAZi_rA/видео.html What "they" have done is make a gigantic mess of everything; mess up the history of relativity; mess up the translating of it into English; mess up the math etc etc.
@@rogeranderton418 I agree with all your comment. Thank you very much. "Galilean transformation" and "Galilean relativity" are nonsense.
Einstein didn't picked up from anybody else but from his first wife Mileva Maric.
I consider the related sentence from Engelhardt, the most thorough and the truest sentence about the theory of relativity. It takes time for one to really understand this sentence (one need to study the history and the mathematics). Poincare (mathematician specialized in complex space transformations and groups) called "Lorentz transformation" auxiliary variables used by Lorentz (Lorentz called them auxiliary variables). Lorentz (in his book and in a letter to Voigt) admitted that he took this change of variables from Voigt (from Voigt's 1887 paper, "On the Doppler's principle"). This of course do not contradict the well-known work done by Mileva Maric on Einstein’s papers (writing the equations, performing experiments on photo-electric effect, etc.).
Reminds me of those videos explaining quantum mechanics using the double slit experimemts.

Did James Clerk Maxwell have this accent?
@@SbF6H No, he was Scottish he was 25 years old when he wrote this paper. I didn't find a good photo of him at this age. For the accent, I will correct it next time
CAN I ask how you did this technically, matlab or?
@@jimimased1894 Yes this is done with Matlab

Cool video but is an aircraft travelling at 0.5c realistic in this scenario. At these speeds have you taken into account relativistic effects?
@@oeq57 You are right the speed is not realistic, but the simulation gives an idea about the Doppler effect. The results for realistic speeds can be obtained by extrapolation. It would not be possible to simulate for realistic speeds directly, it would take forever. The relativistic effects are neglected.

Very nice job, wish we could have a photo and voice sample of the mid-nineteeth century, 25-year-old, Scottish genius.
You are right. I couldn't find a good photo of Maxwell at that age.
@@profhalimboutayeb Right. Tough to find an 1856 photo! JCM is a hero of mine.
@@rogermartin8411 What a century. Faraday, Thompson, Maxwell.
Gauss and Riemann and Cauchy too Plus Hamilton! Can’t forget W. R. Hamilton.
I'm sorry, but this is a bit shit TBH.
Amazing work! As a fellow computational physics enthousiast, I applaud you taking the time for this! There is only few people who want to set the history of physics straight and you are one of them.
Great video! Also relativity is cheered up because the transformations make the Maxwell-Lorentz electrodynamic equations lorentz covariant BUT the full Maxwell-Hertz equations are GALILEAN INVARIANT. Also Weber's Theory published in Maxwell's Treatise is Galilean Invariant. The idea alone that physics have gone off rails more than 100 years ago, makes one brain explode.
Excellent 👌👍🏻
