Russell, you appear to be a different duck given the variety of stuff
you post.
But in an interesting way I figure.

This seems interesting but I'm always skeptical of the idea of
'non-lethal' weapons.
The problem of course being the every human body is completely different
and
in different stages of health. It makes the idea of producing a weapon
that is
effective enough to be useful on the strong and healthy without seriously
injuring
or killing everyone else hard to imagine.

I also think the last picture has some issues. There's no feed horn/LNB
only a small
aperture in the center. However the panel is flat. If it were a phased
array (flat)
then there is no need for the emitter in the middle. If it's not, the
flat panel is pretty much useless.

Just my observation. Oh, also the guys almost seem to be working not to
laugh.
It's pretty oddly posed.

  The heading is in the claim in the link below.
  The reality is ... ???


  http://www.wired.com/news/technology/0,72134-0.html?tw=rss.index



  3mm microwave causes skin heating to pain threshold with user
  tolerances of
  3 to 5 seconds max. A number of pictures, some or all of which may or
  may
  not be genuine. Even has named people from Sandia labs doing demos.
  The
  claimed cost of $40 million over 10 years is too low or too long or
  means it
  doesn't really work very well. Nobody spends "so little" on something
  with
  such promise or takes so long if it works.

  No non lethal weapons are, of course. Some are less lethal and some
  aren't
  weapons.

  Gargoyling the persons' names shows that the picture of the small
  area ADS
  (active denial system) appeared eg here


  http://blog.tmcnet.com/blog/tom-keating/technology-and-science/ray-gun-protects-nuclear-power-plants.asp

  in July 2005 with their names and lots of details as a nuclear power
  plant
  protection system - so there is indeed nothing new about this system.

  Sandia themselves have a June 30 2005 news release here


  http://www.sandia.gov/news-center/news-releases/2005/def-nonprolif-sec/active-denial.html

  with another of the photos from the "latest news"
  and a marvellous 300 dpi 988kB 5 MP JPG here of the two with their
  toy.


  http://www.sandia.gov/news-center/news-releases/2005/images/nonlethal-weaponry.jpg

  5 MP image EXIF says it was taken on May 19 s005 and has been through
  Photoshop.

  IF this is real one could learn much from this image.
  Not quite pocket portable.
  Feed method of the 'dish' is unclear to me.
  A 'dish' this size on a 3mm device implies a gain and a degree of
  focusing /
  that defies imagining. The military vehicle mounted system in the
  wired
  release is larger again.

  FWIW

  Russell
