A group of researchers managed to envelop the United States claims to be the object of a three-dimensional (3D) to make it invisible from all angles. The study was led by Andrea Alu along with his colleague from the University of Texas at Austin, they practice it on a 7 inch long cylinder that is in his private lab for being invisible on micro-wave light directed at the object.
This process uses its own skin which is called as plasmonik material that creates a ' negative image ' object that is being covered to make it invisible. However, this experiment can be done in the new microwave from the electromagnetic spectrum, rather than visible light.
Although this technique is not yet working on the spectrum of visible light, this approach could be applied to improve the view on a microscope light with wavelengths smaller again.
