Does this make sense to you ?

Posted by beppe61 (A) on April 19, 2015 at 22:41:52

Hi !
i am trying to understand a little about cables science.
I found the interview in the link but there is a point that i do not understand.
If i am not wrong the designer talks about a difference in the signal speed through the conductor and through the dielectric, causing a time disalignment of the two signals, if i have understood correctly of course.
And he says that they have found a specific metal alloy for the conductor to reduce the speed in the conductor and align it with that in the dielectric ?
However ... my question is pretty basic and maybe very trivial, i am a beginner.
Does a signal travel in a dielectric that, by its nature, is not conductive ?
How is it possible that a signal, that in the end is a voltage, can propagate through a dielectric ?
what i am missing ?
Thanks a lot indeed for any welcome and appreciated advice.
Kind regards,
bg
