Perfect invisibility

The scientists succeeded when they first crushed the object perfectly, dislodging the cylinder tube 1 centimeter from the microwave.

Many attempts to 'cloak invisibility' of objects have been performed in the past, but none of the experiments are perfectly stealthy, as all still reflect some light, which causes the illusion to be incomplete.

The operational pattern of the diamond cloak

The idea of stealth was launched in 2006 when John Pendry of Imperial College London and David Schurig of David Smith of Duke University introduced the theory of 'change optics' in the journal Science. , and then conduct experiments using microwave materials.

The report began a series of studies on the ability to steal objects, and the groups performed at different wavelengths.

However, to date, none of this group has achieved full stealth capability as described.

BBC reported that Smith's team and fellow Nathan Landy at Duke University changed tactics, this time re-researching the microwave with the goal of creating a stealth layer without any reflections.

They used the invisibility cloak, which allowed light to travel around the cover without reflections.

In the experiment, Smith's group succeeded in dislodging a cylindrical tube of 7.5 cm in diameter and 1 cm in height.
