Invisibility Cloak Could Be Coming Soon With The Use Of ‘Metamaterial’

Scientists in the UK have demonstrated a flexible film that represents a big step toward the “invisibility cloak” made famous by Harry Potter.

The film contains tiny structures that together form a “metamaterial”, which can, among other tricks, manipulate light to render objects invisible. Flexible metamaterials have been made before, but only work for light of a colour far beyond that which we see.

Physicists have hailed the approach a “huge step forward”. The bendy approach for visible light is reported in the New Journal of Physics.

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.
