    Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a material with nano-size particles that can enhance specific properties on the object’s surface.
    While the research might not lead to the invisibility cloak 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, similar to the size of a tennis ball 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.
    The underlying design approach has much wider applications, ranging from microwave to optics for the control of any kind of electromagnetic surface waves.
