This will give 5 kV/m at 50 meters. Perhaps this won't break the auto electronics but a continuous pulse stream might cause the electronics to malfunction as long as the pulse stream hits it.

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?
