Subject: A paper on FTL

There is an interesting paper about experiments describing
faster than light effects. To summarize, it gives a solution
near what I have explaned before here. There is no group
velocity larger than c in these experiments (even if Bessel
beams can do that).

To get the paper, go to: xxx.lanl.gov and then choose:
Physics, abs. When you have the abstract page, choose
the form of the file: LateX, Postscript or Adobe PDF.

Title: Comment on "Observation of Superluminal Behaviors in Wave Propagation"
Authors: Murray Peshkin (Argonne National Laboratory)
Comments: 2 pages, latex. Revised to add a remark on the experiment and to
  correct typos in several equations
Subj-class: Optics
\\
  Mugnai et al. have reported an experiment in which microwave packets appear
to travel in air with a speed substantially greater than c. They calculate the
group velocity of their packets and find that it agrees with their 
experimental
result. That calculation is incorrect. A correct calculation gives a group
velocity less than c. The reported experimental result cannot be reconciled
with the Maxwell equations.
