Here's a simple question.

In Elecromagnetics there are lots of relatively simple experiments
that can demonstrate the various principles and fields.

But I've never seen one that can directly demonstrate a displacement
current. The usual argument seems to be that since the displacement
current hypothesis is necessary for Maxwell's equations to predict
electromagnetic radiation and since said radiation is known to exist,
therefore we doan need no steenkin' direct demonstration of a
displacement current.

Does anybody here know of any direct experimental demonstration be it
simple or complex of the existence of a true displacement current.
Even a reference to a paper where someone has done it?

You might like to look at my website http://www.dualspace.net. Look at
paper #1, "Permittivity" for a practical demonstration of displacement
current. .
There you will see a picture of a commercial vacuum capacitor rated
over 135 amperes of AC current and over 5,000 volts. The current is
given by C dV/dt = dQ/dt = I.
The current is being carried by charge pairs *in the vacuum* not as
charges sitting on the plates, as I tried meticulously to demonstrate
in the rest of the paper.
Notice from the analysis I was able to find the Youngs modulus Y and
mass density rho which together give the transmission velocity of c.
The virtual pairs make Espace or pairspace that actually carries
signals now credited to the empty vacuum.
