Hi Thomas,
The statement that:
6. The current that "flows" in a dielectric, otherwise known as
displacement current,
contradicts:
What RF current is NOT is the transverse electromagnetic wave. That
is, once the effect is in the ether there is no RF current.
All alternating current seeks to escape out into the void of space.
Frequency merely tailors how effectively this is accomplished.
Current arises through the movement of charge (fairly built into a
physical process). This movement can be quite far away (even to the
point of the Butterfly effect) but still influence other physical
charges to mimic the movement. Hence there is the appearance of
continuity of the current even though there is no physical transport
capable of conducting that physical charge across that space.
In any current, if you could isolate and observe a specific, physical
charge; then you would observe that it travels no more than a meter a
second (if that fast). However, if you could isolate and observe two
specific, physical charges; then you could observe that when one
moved, the other would mimic that movement with nearly no delay and
the effect of that continuity is only limited by the speed of light
and the distance between those charges.
