This comes from LiveScience Journal:
"The proposal involves using plasmons -- tiny electronic excitations on the surfaces of some metals -- to cancel out the visible light or other
radiation coming from an object.
"A proper design … may induce a dramatic drop in the scattering cross-section, making the object nearly invisible to an observer," Nader and Alu
write in a scientific paper that was made available to the public Feb. 14.
But cloaking ability would depend on an object's size, so that only with very small things -- items that are already microscopic or nearly so --
could the visible light be rendered null. A human could be made impossible to detect in longer-wavelength radiation such as microwaves, but not from
A spaceship might be made transparent to radio waves or some other long-wavelength detector."
Though a long way off from being the famed weapon of the Star Trek world, even the smallest such device is amazing.
