Researchers at Duke University have developed a device that bends microwaves around an object in such a way as to make it seem that the object is not there at all. The device cloaks a 0.4 in. (10 mm) tall metal cylinder that is overlaid with patterned metallic materials called metamaterials, which enable the device to bend the waves around the object. The device uses microwaves instead of visible light because microwaves have longer wavelengths and interact better with metamaterials. The researchers are no working on a larger version that will cloak an object approximately the size of a toaster.

I NEED a cloaking toaster!

You mean the cloaking feature doesn't come standard?
