First application that comes to mind is hiding that 40M SteppIR on your
roof.

Or, more fun, how about having your entire house disappear along with
your CW transmissions? Not exactly RFI but ...


Hi John,

The link above is rather facile in its reporting, but so are most of
the pages provided by Dr. Smith (there's something of "Lost in Space"
about them).

Anyway, the science behind this news is found at:
http://www.ee.duke.edu/~drsmith/neg_ref_home.htm
which relates to topics I've offered in this group in the past 3 or 4
years. It comes from the photonics of negative refraction abstracted
to RF.

Boeing Phantom Works, here, has already done the bulk of the work and
their devices are displayed at the pages above (without citation), are
better documented at:
http://www.boeing.com/news/frontiers...gust/i_tt.html
and
http://ceta-p5.mit.edu/metamaterials...r_apl_2003.pdf

The last is a real paper, not the fluff going around in the popular
press.
