Military Eye New Invisible Cloak Breakthrough

By Tony Ibrahim | Friday | 27/01/2012

Scientists in the United States are celebrating their recent success in masking a 3 dimensional object, with the breakthrough harbouring great military potential.

The breakthrough could enable a 'Super Stealth' mode to be enabled in War Planes
The Scientists working at the University of Texas in Austin were able to cloak an 18cm cylinder from light in the microwave part of the energy spectrum. Such technology could cloak a war plane by concealing it from the microwaves used in radars.

"[The cylinder] is a real object standing in our lab, and it basically disappears," said group's spokesperson, Professor Andrea Alu.

Although it would evade microwaves, the plane would still be visible to the naked eye. However, according to the SMH, Alu believes the findings are a breakthrough in plasmonic meta-materials as they prove a cloaking effect is possible.

Plasmonic meta-materials are made up of metal and non-conductive synthetics. Their nanometre-size is far smaller than the wavelength of light that strikes them, and when they are exposed to incoming photons, they excite currents which cause the light waves to scatter.

The 'cloak' itself is more like a case that has the exact opposite properties of the object it is covering.

"When the scattered fields from the cloak and the object interfere, they cancel each other out, and the overall effect is transparency and invisibility at all angles of observations," said Alu.

"What we are thinking about is not necessarily cloaking the whole warplane but some hotspots, a part such as the tailplane … because it reflects most of the energy [from microwave radar]."

Alu believes the breakthrough is a step in the right direction for plasmonic cloaking, but admits there's still a lot of work to be done.

"Our goal was just to show this plasmonic technique can reduce scattering from an object in free space. But if I had to bet in five years what kind of cloaking technique might be used for applications, for practical purposes, then I would say plasmonic cloaking is a good bet."

LG Australia has finally rolled out their 65" Ultra High Definition TV offering in Australia and what you get is a TV that delivers a quantum leap in TV technology and surprisingly a significantly improved sound system that is delivered from pop down speakers but the big question is whether it is worth $6,999.
