| Summary: | Currently, technologies are able to hide the objects on the radar screen by covered them with a special kind of paint to absorb the electromagnetic waves to make them become stealth. But what if one can hide all these visually objects from
the naked human’s eyes? Thanks to the development of new technologies, scientists have been constructed successfully new type of materials called metamaterials. One of the interesting characteristics of these new materials which is totally different from the conventional materials is the electromagnetic particular trait, the negative refractive index. With this, new applications have been studied to create the structures which could “bend” the light or electromagnetic waves around the objects to make them invisible literally under the Sun. |
