of the perks of attending the International Microwave Symposium (IMS), hosted by the Institute of Electrical and
Electronics Engineers (IEEE), is that you are given the opportunity to see a part of the history of microwave
engineering. At the two IMS shows that Melanie and I have been to (2009 and 2011), a portion of the contents of
National Electronics Museum
in Linthicum, Maryland, (only a few miles from the Baltimore Convention Center)
Safely locked behind protective glass and guarded by a paid sentinel are relics of our
profession's past. Prototypes of magnetrons, circulators, filters, phased array antennas, traveling wave tubes,
waveguide, oscillators, and a host of other devices dreamed up by those whose names are on the "Honor Roll"
plaques, are on display. Some items are simply labeled with part numbers, like with many of the vacuum tubes,
while others have information sheets with lots of detail.
Unlike at the
show when I only photographed a few of the exhibit items, this time I got every one. Getting really good
resolution was not possible because of having to shoot through glass (and I forgot to being the monopod with me),
but the lettering of most of the labels is readable if you click on the thumbnail to enlarge it. Send me an e-mail
if you need the full resolution original image. Maybe you will see yourself in one of the photos if you were there
on Tuesday. Enjoy!
Remember that it is the exhibiting companies who are picking up the tab for this and making it available to

(hem-usa.org) and took control when the name was accidently allowed to expire. The correct URL is now
(the URL printed on the brochure handed out at the show is the old one).
