Free Energy from Electromagnetic Wave Fields

Respectively ZL, are you serious?  If a measurement is taken at the other end of the grounded input on the Tline, of course you will find a negative going pulse as compared to the applied pulse. But this is like looking at the outside of the rods on the wave machine at the starting pulse and then moving around to the back side of the table to look at the inside of the rods when the output pulse arrives!

Remember, you have suggested the option to measure the output at the bottom end of the T-line output, not me! If you are suggesting that this is a stupid idea, then why did you suggest it as an option in the first place? I have a feeling that now this is becoming an ego question, which is not nice. If you make a mistake and you are trying to hide it and cover it up with further obfuscations and false statements, instead of just simply acknowledging it, that will not make you look smarter. And it will not motivate me to show you things either, although I am trying to be patient...

You were trying to set up a simulation that would at least approximately behave as the wave machine, and for now you were able to view the signal at the input and at the output only. It does not matter which point you chose in your circuit to represent the output of the wave machine, as long as the signal that you measure there is analogous to the output signal of the wave machine.

We don't need to look "inside" the Tline to analyze the results we see at the ends.

We don't. But we do need to look inside the T-line for you to see and understand that the circuit partzman1.png properly simulates the wave machine, and the same wave amplitude propagates inside the T-line that propagates inside the wave machine.   

The sims I've provided as well as the ones you have provided utilizing the lossless Tline model do not agree with the wave machine.

The partzman1.png version does agree with the wave machine! I have not prodded you to watch the video at the critical point frame by frame in vain, or because I am bored and have nothing better to do. If you would have opened your eyes, used simple clear thinking and a bit more humble approach, you could have seen that the amplitude at the output of the wave machine is also double of the signal amplitude that propagates inside the transmission line.

The reason for me prodding you to peek inside your T-line is again not in vain, but because this is the most convincing way to show you that the circuit accurately models the wave machine. You will see that the wave amplitude inside the T-line is the same as the original input pulse. This will also finally prove that Dr. J.N. Shive's statement that "the reflected wave from an open ended transmission line is a reflected replica of it's original self" is indeed correct, just you did not set up your circuit properly, and you still don't understand the results that it displays. 

There is NO evidence of wave superposition at the output of the un-loaded wave machine as compared to the un-loaded simulation.

There IS! Watch the video frame by frame when the right side of the impulse has just touched the end, and measure the amplitude. Then go on watching frame by frame until the amplitude becomes maximum at the output, and measure this max amplitude again. You will see that this second amplitude will be 2x the first. That can only happen if there is wave superposition at the very end of the line. Should I really spoon-feed every minute detail for you to understand?

ZL,

Let's just cut to the chase!

Please point out what is missing in the video clips in my post #37 in reference to your above comment.  "Has just touched the end" of what?  This obviously must be at the beginning but I honestly don't understand where this reference amplitude point is!?!

What I see in the clips I supplied previously is a peak amplitude of the rods created from input by the professor at the start of the wave input.  Then as the wave progresses down the line, I see the rods reach a peak amplitude at the output that to me appears to be reasonably equal to the peak at the start of the wave input.  Then I see the return wave reach the input with a slightly lower amplitude than the starting amplitude.  It doesn't get any more clear than that IMO.

So, in order for you to get your point across, perhaps you (or anyone else) would like to take the time to freeze frame the wave machine video to make your point graphically because I just don't get it!

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.

In this specific case we are not on the same amplitude instead

Thanks itsu, I started thinking that maybe my English sucks, and that is why my explanations don't seem to help Partzan. It is not enough just to look; one also has to see what he is looking at.

The wave machine is not an ideal Tline. There are losses in it, which are quite significant and observable. The pulse amplitude near the end in the very first cycle is already significantly lower than the original input amplitude. If one wants to observe the momentary wave superposition at the output then the comparison must be done right next to one another, to avoid the falsifying influence of damping during the propagation.

How and where to observe this phenomenon has been meticulously explained in my last post, if one cares to read and understand. I can't get any clearer than that.

Last call for action:

Is there anybody who can modify the LtSpice Tline circuit so that we can see into the transmission line and observe the shape and amplitude of the pulse that propagates in it? So far we can see that only at the input and output of the line, but we want to peek into it at an arbitrary position along its length.

If no solution comes forward, then I will post it later today or tomorrow, and we can discuss the case further and explain what is happening and why in more details.
