That’s a Wrap! The 2013 IEEE EMC Symposium

 

BLUF—that’s "Bottom Line Up Front" for those that don’t speak acronym-ese—the 2013 IEEE International Symposium on EMC was another smashing success! Denver is a great town for a convention, the facilities were excellent and as always, the Symposium committee pulled it all together and put on an outstanding show. If there were any hitches or glitches, it sure didn’t show. I’ve … [Read more...]

Elephant in the Test Room #1 Continued – The “Money No Object” Approach to Fixing the Under-Test Situation

 

Read other posts in the "Elephant in the Test Room" series here.Recap on this threadThe room: MIL-STD RF immunity testing – 1-18GHz 200v/mThe elephant: Everyone in the room is aware that a significant fraction of the ‘calibrated’ 200v/m test field is actually created at the wrong test frequency.The culprit: Notoriously high ‘start of band’ harmonics produced by all octave band … [Read more...]

Another IEEE International Symposium on EMC

 

By the time you read this, you SHOULD be at the annual IEEE EMC Society’s Symposium in Denver, CO. At least I hope you are! I know that the fiscal environment is tight these days, and if you happen to work for the US DoD and/or are a contractor supporting the US DoD, funding travel is almost impossible. I suspect that numbers will be down, but hopefully not down too much. … [Read more...]

Do We Only Believe Things that Match Our Opinion?

 

Whoopee! I finally got some feedback that people actually read some of the stuff I write. I received several great comments about a previous post titled: Electromagnetic Fields Don’t Exist. I’m not sure they liked what I had to say, but most were nice about it. I apparently excited some nerves. That happens when they’re exposed to electromagnetic radiation. I’m using … [Read more...]

I Can’t Believe I Just Cooked My Pinna

 

In the previous post, I was discussing cellphone RF safety and the fact that we really don’t know what level is safe and what’s not. Those individuals that go around with a cell phone or Bluetooth device glued to the side of their head will be happy to know that the FDA and the FCC are concerned about cell phones cooking their outer ear (the pinna). They have apparently … [Read more...]

Shooting Stars: Up-and-coming EMC Engineers Ready to take on Challenges in the Field

 

By Vinti Singh During playtime, while Benjamin Orr’s classmates were playing superheroes, cops and robbers or house, Orr was playing engineer. He would use crayon drawn “schematics” to “rewire” the playground. His curious classmates asked what he was doing, and soon after he was leading a crew of young technicians through the jungle gym. About two decades later, Orr has moved … [Read more...]

Electromagnetic Fields Don’t Exist!

 

Some time ago, I made a big to-do about smart electric meters and the fact that they might be hazardous to our health. The general response I got was: you got to be kidding. Sometimes from the more heavily invested the response is: there is insufficient evidence to make that conclusion. The World Health Organization concluded that electromagnetic fields from cell phones and … [Read more...]

OMB Circular A-11: Preparation, Submission and Execution of the Budget

 

What’s that you say? What does OMB Circular A-11 have to do with anything EMC related? That’s a pretty good question, and one that I would have asked myself. Until I read (because it was pointed out to me) section 31-12 of the latest edition of the Circular. It starts off:“The value of radio spectrum required for telecommunications, radars, and related systems should be … [Read more...]
