Years ago, quantum tunneling was reported to have passed
information at faster than the speed of light. I haven't
heard anything about that lately.

I think there are two main avenues of thinking on the phenomenon known
as quantum tunneling being faster than the speed of light. One is
that other dimensions are involved. Data is not traveling faster than
the speed of light, it is just taking a short cut. The other is that
the data was wrong.

As quantum tunneling occurs millions to billions of times per second
in every antenna in the world, it would seem that faster-than-light
operation would have been observed by now (something of an oxymoron
there in this irony, isn't it?).

"For (quantum tunneling) effects to occur there must
be a situation where a thin region of 'medium type 2'
is sandwiched between two regions of 'medium type 1'"

In an aluminum/copper antenna, what exactly makes
up the two medium 1 regions and what exactly makes
up the thin region of medium 2?
