My coworker wonders what it would do to pedestrians with pacemakers. As for hurting the standard issue person? If you can't see it, it can't hurt you, and it? How about a big tazer to zap the car? Or, ionize the air with a laser and then transfer charge to the car though that. The car will arc over to ground, making it's own EMC pulse and possibly stopping it.

Amazing how much power EMC can really have over the world today. My question though is what if other vehicles are in the path of the EM Field? I wonder how much of a clear shot is required for accuracy? Also, the effects on the vehicle firing the EM Field and all the people who may also be induced in it? Any studies done to prove or disprove that the EM Field is harmful? In my experience and study a field with as little power as 100V/M can have serious affects on human beings..... Just my two cents.

An EMP device like this can generate a 1-2 gW pulse, or so I have read. Given 50 kV across a dipole you will get 35 megawatts. Directed with a gain of 10 dBi this will give 2000 V/m at 50 meters. Is this enough to stop automobile electronics? Dave Cuthbert Micron Technology From: [email protected] [mailto:[email protected]] On Behalf Of James Youngman Sent: Tuesday, July 13, 2004 10:03 AM To: [email protected] Subject: EM Disruption of Automobile Electronics http://www.ieee-pses.org/symposium http://www.emc2004.org/ Most Esteemed EMC Gurus, First post from a long-time suscriber. Subject is automotive EMC and the intentional disruption of microprocessors in automobiles to disable vehicles, presumably during chases. In an article in the Guardian (UK newspaper), Dr. Giri describes his newly invented device; the article is at http://www.guardian.co.uk/crime/article/0,2763,1259138,00.html This was also reported on National Public Radio ( http://www.npr.org/features/feature.php?wfId=3327049) (watch for split URLs). Knowing the lengths that the automotive EMC community goes to to prevent this exact effect, and having been involved in similar "pursuits" of my own, I have my doubts, but am interested in the opinions of others. Has Dr. Giri found a back-door path into automotive microprocessors? Thanks, Jim This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
