Tunneling violates special relativity? Who knew!

Except it doesn't. And they don't seem to be talking about quantum
tunneling, they seem to be talking about frustrated total internal
reflection, which is classical. I.e. they're claiming that Maxwell's
equations violate special relativity, as far as I can tell.

Given that SR was written to make Newton (less gravitation, G=0 in SR)
compatible with Maxwell, one expects things will not go well for the
Germans. The literature is rife with superluminal this (phase vs.
group velocity, EPR paradox) and footnote relativistic stuff that
(electrons in graphene). Causality is *never* violated. There is
*no* superluminal transmission of information.


But if it DID transfer information FTL and STILL did not violate
causality THEN they really would have blown a big hole in
Relativity, now wouldn't they?

"The evanescent modes and tunneling violate the theory of special
relativity" "We demonstrate the quantum mechanical behavior of
evanescent modes (with digital microwave) signals at a macroscopic
scale of the order of a meter and show that evanescent modes are well
described by virtual photons as predicted by former QED calculations."

I don't see anything in the abstract or article that says they
transluminally conveyed information. "More studies are needed" is not
a reproducible empirical observation.


So then why all the fuss?
