Harry Potter-style invisibility cloak a reality soon?

March 28, 2013 13:25

Scientists have inched closer to developing a 'Harry Potter' style invisibility cloak after devising a revolutionary new method to make objects disappear within a limited range of light waves.

Researchers at the University of Texas developed a thin material called a 'mantle cloak' which makes an object 'invisible' after being wrapped in it.

However, the effect only applies to a limited range of light waves - specifically microwaves, 'CNN' reported.

Scientists covered a cylinder about a foot long and an inch or so in diameter with the material. Microwave detectors could no longer plainly 'see' it, although it was still visible to the human eye.

Researchers said the same principle could be transferred to the range of perceptible light, which would then make objects invisible to the human eye.

The effect only covers a very small band of electromagnetic waves at one time, and in the visible range of light, it would only work on objects much thinner than a single strand of hair.

According to the researchers, the new cloak is made of a sheer, handy material that can be applied to many surfaces, even irregular ones.
