Found this additional article with comments by Prof. Nimtz
about his experiment;
Communication faster than Light

An experiment at the University of Cologne is putting
accepted scientific knowledge to the test.
According to accepted teaching signals cannot be transmitted
faster than light. Some even believe that Einstein's Theory
of Relativity could be broken if light moved faster. At the
University of Cologne physicists have begun to shake up this
theory.
The spectacular experiment took place in a laboratory of the
second Institute of Physics. Prof. Dr. Nimtz and Mozart's
40th symphony are our main protagonists in this experiment.
At first the music is put piggyback onto a carrier wave, in
this case a carrier wave of ten gigahertz. The carrier wave
travels over a cable into a funneling antenna then a little
through the air and into the reception antenna. It
follows another short thin tunnel - where the signal should
stop.
According to the laws of physics the microwave does not fit
through the tunnel, it ought to be reflected back. Despite
this the signal mysteriously slips through the tunnel. And
in doing this moves faster than is possible by our present
understanding of physics.
The Nimtz Experiment is based on one of those bizarre
tunneling effects by which quantum physics keeps confounding
our every day experiences. If you kick a soccer ball
against a wall it bounces back.
But a wave packet can reappear behind the wall. It will be
weaker but faster than before. This can't be explained but
it is a measurable effect. Information can also be
transmitted like this.
Prof. Dr. Nimtz explains it thus: "We have sent such a
signaling impulse through a test range and measured: What is
its speed in comparison to the speed through the air? The
speed we measured is 2.46 times the speed of light."
The type of signals are the same as in use in mobile
communications devices or which are used for data transfer
between computers. It also works for the transmission of
more complex information like a whole symphony.
"What these experiments have shown is that you can in
principle look into the past. And it is also possible to
reverse cause and effect", says Prof. Dr. Nimtz and
explains:
"According to the theory of relativity a second observer in
another inertial system (frame of reference) can see my
signal exit the target before it was emitted by the source.
This means you can look into the past because you are moving
faster than light, which is the speed at which the effect is
moving, the event."
Guenter Nimtz is not claiming to have refuted Einstein.
Other physicists have repeated his tunneling experiments and
confirmed that the experiment works. The layman may believe
this or not: "Faster than Light" has become a hot topic in
physics.
