The ultimate in camouflage for military purposes would be complete
invisibility. Invisibility has been a major factor in fiction going
back to ancient Greek mythologies to contemporary science fiction.
While we are far away from space ships capable of intergalactic
travel like Stargate Atlantis, a clocking device may be closer than
Metamaterials refract light at a negative angle, rather than
refracting light like normal materials that can be seen. The
properties of metamaterials allow scientists to bend light around
objects making them invisible to the naked eye. DailyTech
reported on similar technology before when researchers at the
University of Maryland were able to cloak
a small 10 micrometer circle making it invisible to the eye.
While 10 micrometers is incredibly small, the scientists hope to
one day scale the size of the cloak to hide people and objects. This
is exactly what researchers at the Britannia Royal Navy College hope
to do, but on a much grander scale. The scientist
are developing a method to render full battleships invisible to
not only the naked eye, but to radar as well. The researchers also
hope to mask the sound produced by the ships as well as its heat
If the scientists are able to accomplish the goal, it would mean
the British Navy would have battleships invisible to the naked eye,
radar, heat-seeking missiles and that produce no noise. If
successful, the only indication that the ship is coming would be the
water displaced by the ship.
