"An invisibility cloak that works in the microwave region of the electromagnetic spectrum has been unveiled by researchers in the US. The cloak works by steering light around an object, making it appear as if it is not there. It is based on a new breed of "metamaterials", which can be tailored to have exotic electrical and magnetic properties not seen in nature. These materials are made up of complex arrays of metal washer-like shapes and wires that are smaller than the wavelength of microwave light and so interact with it. "
