X-Message-Number: 14092 From: Date: Thu, 13 Jul 2000 17:09:12 EDT 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. << Paper: physics/0006034 From: Murray Peshkin - 630-252-4061 <> Date: Tue, 13 Jun 2000 22:19:00 GMT (2kb) Date (revised v2): Fri, 16 Jun 2000 16:51:29 GMT (2kb) Date (revised v3): Fri, 23 Jun 2000 15:21:39 GMT (2kb) 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. \\ >> Yvan Bozzonetti. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=14092
