Scientists have inched closer todeveloping 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. Scientists covered a cylinder with the material. Microwave detectors could no longer plainly ‘see’ it.
