Electromagnetic Compatibility Society (EMC)

Electromagnetic Compatibility Society (EMC) The purpose of the EMC society is to further education, excellence and the EMC presence in the Huntsville area. By coming together we can increase the bandwidth of our member’s knowledge by learning from one another. For more information about the local chapter, contact EMC Chairman, Jack McFadden.

Buried Capacitance in Printed Circuit Boards

You are cordially invited to a Technical Presentation by the IEEE Huntsville EMC Chapter. Mr. John Andresakis of Oak-Mitsui Technologies, will present “Use Of Buried Capacitance Layers In Printed Circuit Boards: Performance And Lessons From A Real World Example”. Meal Sponsor: Mr. Mike Kirk, Agilent Technologies, providing “Fried Chicken With All The Fixin’s”

Signal Integrity and EMC – A Twisted Pair

The Huntsville Chapter of the IEEE Electromagnetic Compatibility (EMC) Society is hosting:
“EMC 2010: SI and EMC – A Twisted Pair” on Tuesday, April 20th at the Von Braun Center.The one day engineering seminar presenter is Dr. Eric Bogatin of Bogatin Enterprises LLC. Dr. Bogatin is an IEEE Distinguished Lecturer (DL) and for the past 20 years has widely taught and authored numerous papers and books on the topic of signal integrity (SI) and high speed printed circuit board (PCB) design…

Abraham Lincoln Assists With EMI Testing

Abraham Lincoln is quoted as saying that if he had eight hours to chop down a tree, he would spend six of those hours sharpening his axe. This presentation is about replacing the axe with a chainsaw. Spectrum analyzer surveys of platform (aircraft, ground vehicles, ships) antennas are the ultimate check that RFI has been properly controlled. As envisioned in MIL-STD-464, an analyzer is connected to a platform antenna and the antenna band is swept, looking for RFI signals. This technique fails when the antenna must be tuned for each frequency of operation. In the past, this was only the case for HF, but today multi-band antennas covering 30-512 MHz are also tunable. The presenters have developed a hardware solution that allows broadband sweeping of a tuned antenna from 2 – 512 MHz (COMM Bands: HF, VHF-FM, VHF-AM, and UHF-AM) without tuning.

Who’s Afraid of Maxwell’s Equations?

The November 12th meeting was held at the ADTRAN Mark C. Smith Conference Center. This was a joint meeting with the local IEEE AES Society Chapter. The presentation was provided by the IEEE EMC Society President Elya Joffe who was in town for the EMC Society Board of Director’s meeting. Doug Parker presented the enlightening and entertaining introduction to our speaker, Mr. Elya Joffe. We had not realized that Mr. Joffe was so well acquainted with Mr. Maxwell and that his new book had reached such national recognition. After graciously acknowledging the introduction, Mr. Joffe’s presented “Who’s Afraid of Maxwell’s Equations? A Practical Approach”.
