Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a composite material with nano-size particles that can enhance specific properties on the object's surface.
Researchers from QMUL's School of Electronic Engineering and Computer Science, worked with UK industry to demonstrate for the first time a practical cloaking device that allows curved surfaces to appear flat to electromagnetic waves.
While the research might not lead to the invisibility cloak made famous in J.K Rowling's Harry Potter novels quite yet, this practical demonstration could result in a step-change in how antennas are tethered to their platform.
It could allow for antennas in different shapes and sizes to be attached in awkward places and a wide variety of materials.
The researchers coated a curved surface with a nanocomposite medium, which has seven distinct layers (called graded index nanocomposite) where the electric property of each layer varies depending on the position. The effect is to 'cloak' the object: such a structure can hide an object that would ordinarily have caused the wave to be scattered.
