At first I was surprised by the bold statements of the authors:
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.
Several QED and QM calculations predicted that both evanescent modes and tunneling particles appear to propagate in zero time.
All three properties - the violation of the Einstein energy relation, the zero time spreading, and the non observability of evanescent modes - can be explained by identifying evanescent modes with virtual photons as predicted by several authors, see for instance references. Tunneling and evanescent modes are properly described by quantum mechanics
The (unpublished) paper's form is `unacademic' (i.e. not TeX-ed...) and at first I had doubts as to the credentials of the experiment. Was it another out-of-nowhere Einstein basher? But further search has showed that this is a paper from a long series of publications involving light and microwave signal processing in unusual setups. For references it suffices to search arXiv for au:Nimtz_G
Signaling faster than light speed? Not only possible but observed?
In the light of a recent discussion with a friend (also on this blog...) how would one describe it in a quantum way? or photons as billiard balls way?
