@Itsu,

Thank you for going to the trouble of producing those freeze frames.  Because of it, I can see the superposition at the output waves.

@ZL,

As you can see, the case is closed.  Sorry to have wasted your time and I wish you the best in your efforts here.

Here is another nice example of why I am generally reluctant to post on this forum (except for brief announcements). Because of the disinfo agents and other over inflated egos here, whose primary aim is to show off their imaginary greatness, to appear as very important inventors and researchers (who already know things), and everything else is just secondary to them. When their ego gets hurt, then they turn into ingrates and enemies (overt or covert).

Partzman is thanking Itsu for going to the 'exceedingly difficult and time consuming trouble' to post the two frozen frames, which I have clearly described how to make (which is fine). In contrast, he is implicitly showing me his middle finger, because his ego has been hurt, and I have offered nothing useful. OK now reader honestly, in my place would you be motivated to teach and help such people? If you would, then you must be a masochist, which I am not.

At a second thought, it is quite possible (and probable) that the challenge of partzman under the guise of asking his question was not a honest intent to learn, but rather a sneaky attempt to discredit me. You know, along the line:

"Let's ask ZL a tricky question upon which many beginners slip up, and which is very counter-intuitive. If he does not know the correct answer we will provide it, and then he will be discredited. People will think that he is clueless and they will ignore his FE principle, thus our (the disinfo agent's) goal is accomplished. On the other hand, if he knows the correct answer, then Partzman will feign to be errr... (how to put it nicely) unbelievably incapable and unwilling to understand the explanations. Our player will also get indignant and put all blame for his mistakes on ZL, so that all these effects combined will hopefully piss ZL off. He will loose his patience, say something offensive, and appear to the uninitiated public as a bad character. Since nobody else would like to be treated like Partzman, people will distance themselves from ZL. We, the great disinfo agents (thanks to our psychologists) will win again. No matter what ZL does, we win! We are the supreme strategists, period."

Why do I suspect such a foul play here, am I an incurable "conspiracy theorist"? And you know that this term "conspiracy theorist" has been perverted by the establishment propaganda to be synonymous with the label of "crackpot", right? Because there is NO conspiracy whatsoever and you must believe that such thing does not exists, and those who claim otherwise should be treated as despicable... I suspect foul play on this thread, because the covert action became overt when despite my precise description, Partzman still feigned inability to see what happens to the amplitude at the end of the wave machine (which I can't believe to be true). While miraculously within few minutes of him asking for snapshots, Itsu provides the requested images (before I get the chance to do the same), so that Partzman can have a seemingly triumphant exit thanking him for solving his problem, "closing the case" and expressing his veiled f-you to me. 
Getting back to our subject, the case of analyzing an unloaded transmission line is far from being closed. We have just started. The case of Partzman's participation may be closed, according to his intent to close the case. If nobody else is interested in the explanation of the rest of the subject, then I am happy to indeed close the case here on this thread, and focus instead on my own work.

But if there are people who want me to finish the related explanations, then let me know, and I will post the rest of the story. My posts were not meant to help Partzman only, but other good people as well, who are interested in the subject now, or in the future.

ZL,

I really don't know exactly how to respond to your last post but I must say something to defend myself because you have severely attacked my character.  You question my ability to "see" what was obvious to you and when I finally do understand and acknowledge the same plus apologize for wasting your time, you rip me to shreds.  I also apologize to Itsu for getting dragged into this by his sincere attempt to help me.

You said "I suspect foul play on this thread, because the covert action became overt when despite my precise description, Partzman still feigned inability to see what happens to the amplitude at the end of the wave machine (which I can't believe to be true)."  This probably means nothing to you but I lost my brother last week and a good friend this week so my mind hasn't been operating as it should.  There is/was no conspiracy, intent to discredit or derail your efforts, or any other harm you insinuate.  You really owe me an apology!

My "case closed" comment had nothing to do with your ongoing explanation of anything you desire to discuss, but simply meant you no longer had to deal with my stupidity.  I humble myself and acknowledge that "I didn't get it" so what more do you want?

You guys are obviously not on the same wave length   


PM, i think ZL means this, see the below pictures at 3.46 m into the video.

Regards Itsu

It would be actually interesting to see if the momentum of the wave doubles as well, together with the amplitude.
It may not contradict the 3rd law of Newton because the momentum of equal magnitude is still there,
but it may be just added to the original due to the reflection.

Telecom, you are a mechanical engineer, right? It should not be very difficult for you then to calculate the momentum and the energy content of the wave pulse. Do you want to perform this calculation and share the results? It would be quite educational for everybody interested.

So far we were mainly discussing the simulation of EM wave pulse propagation in a transmission line. But similar simulation can be set up for mechanical waves as well. If you prefer to study the mechanical waves seen on the video, and would like to play with it (at least virtually) then here is a nice simulation that will let you do just that:

Wave Machine Model
http://www.opensourcephysics.org/items/detail.cfm?ID=10481
Download the "download 1694kb.jar" double click on it, and you are ready to start playing with waves and observe their motion in real time, just like the Prof. did in the video. The parameters can be changed as well, which will let you get a good feel of how waves behave under different conditions.

If on the other hand you (or others) want to play with an upgraded version of the T-line simulation in LtSpice, which lets you see the wave inside the transmission line, here is the diagram and the wave plots it can display: Split_Tline1.png see at the bottom.

It is very easy to solve the problem of measuring the wave inside the Tline with simple clear logic, something like this:
-Let's assume that the Tline is a piece of coax cable, to make it easy to visualize.
-Let's measure the voltage in the middle of the Tline; How to do it?
-In order measure it, we would have to cut it in the middle, otherwise we can not access the inner conductor.
-OK but then will the wave propagation not change? Not significantly if we solder them together nicely after leading a tap wire out which is soldered to the inner conductor, and then joining the two inner conductors together, and also the two outer ones without any gap.
-This way we model a single Tline with two Tline segments of identical characteristic impedance connected in series. This is what we see on the schematic. Both Tline segments are identical and have a Td=1.25us, which together will produce a time delay of 2.5us in this case.
-Now we have access to a measuring point that is in the middle of the cable, and we measure Vtr at that point, which is the blue trace on the graph.
-OK, but how can we measure the amplitude inside the Tline at an arbitrary point, let's say at x*L distance along the length L of the line, where 0<x<1? That should be easy: use Td1=x*Td for the first Tline, and Td2=(1-x)*Td for the second Tline. Td is the total time delay of the complete line, which is in our example 2.5us (but you can change that to suit your needs).

If you play with the simulation a little bit and observe the waves, you will realize, that the amplitude inside the Tline is identical with the original impulse just as the Prof. stated, except that it gets doubled at the output for a brief moment where it is reflected, and the same happens at the input when it returns. This is a simple demonstration of local wave superposition. It is local in this case and temporary, because it happens only at within len/2 distance from the ends (where len is the length of the pulse). If you want to examine the gradual change of amplitude within this critical region, then chose Td1 and Td2 to place Vtr somewhere within this section.

How can we have a wave superposition or interference if there is only one single wave pulse? Don't we need at least two waves to be added together? In this case the front side of the wave pulse turns back at the end to overlap with its own back side (tail). The two pulse segments propagating in opposite directions will get superimposed just the same way as if they were two independent waves. That is why we observe interference only at the very ends, and get double amplitude.

Now comes the key question:
Brilliant! We have produced wave superposition in direct phase and got a pulse of double amplitude. According to the FE principle from wave fields this supposed to contain excess energy... right? Well, think twice! Think hard, because this is a tricky and very counterintuitive property of waves! You can slip up here again very easily. If you think there is excess energy produced, then explain why, and how much. If you think there is no excess energy produced, then again you should be able to state the reason, and explain it. Remember, we are not interested in entertaining rosy illusions and chase fake FE devices, but in generating real excess energy. The first step towards that goal is to weed out false hopes and illusions.
