Scientists progress towards cloaking device
{{date|October 20, 2006}}

Scientists from the [[w:United States|United States]] and the [[w:United Kingdom|United Kingdom]] have announced that they have invented a way to make things invisible in [[w:microwave|microwaves]]. The new mechanism is currently operated by what scientists call "metamaterial" which is a new material that has been created in a laboratory and can decrease the scattering as well as the shadow cast by a specially designed copper cylinder. This means that the cylinder is partially [[w:Cloaking device|cloaked]].

"It's not exactly perfect &mdash; we can do better &mdash; but it demonstrates the mechanism, the way the waves swirl around the centre region where you want to conceal things," said [[w:Duke University|Duke University]] scientist, David Smith. The findings have been published in the October 19 edition of the journal [[w:Science (journal)|''Science'']].
