Scientists Make Progress Towards Invisibility

British researchers have made progress toward developing materials that are able to bend light around them and render them less visible:

Metamaterials work by interrupting and channelling the flow of light at a fundamental level; in a sense they can be seen as bouncing light waves around in a prescribed fashion to achieve a particular result.[...]

Ortwin Hess, a physicist who recently took up the Leverhulme Chair in Metamaterials at Imperial College London, called the work "a huge step forward in very many ways".

"It clearly isn't an invisibility cloak yet - but it's the right step toward that," he told BBC News.
