Harry Potter's invisibility cloak can become a reality

British scientists have invented a new material capable of creating an invisibility cloak of Harry Potter characters. This new material, called 'Metaflex' in the future, can be used to produce fabrics that are capable of manipulating light.

According to the new Journal of Physics, this metamaterial has the ability to bend and leak light causing objects to become invisible at longer wavelengths. Meanwhile, the type of visible light is a bigger challenge because its short wavelength requires super-atom atoms to be very small.

The Harry Potter character used the invisibility cloak in the Fire Goblet episode.

So far small atoms can bend light so they are only produced on a flat, hard surface and are not suitable for fabric.

However, scientists at the University of St. Andrews, Scotland, believes they have overcome this problem. They have produced a flexible " membrane " metamaterial by using a new technique to release super atoms from the hard surface they built above.

Metaflex can operate at a wavelength of about 620 nanometers, in visible light. Scientists believe that overlapping membranes can produce a flexible " smart fabric " that underpins an invisibility cloak.

Other applications may include super lenses much more efficiently than conventional glass.
