Cloaking technology can bend light around itself could hide objects from sight. Imagine how the world would look like when Nanotech scientists are able to bring electromagnetic devices in the market. And news is that this is not impossible now.
Beyond possible military and lifestyle uses (remember the science fiction senses Hollywood movies), scientists are working on a material that could eliminate hurdles in communication signals. The material is easier to make and has a far greater bandwidth. It is made from a so-called metamaterial -- an engineered, exotic substance with properties not seen in nature. Metamaterials can be used to form a variety of "cloaking" structures that can bend electromagnetic waves such as light around an object, making it appear invisible.
As per BBC news, a US-British team of scientists has successfully tested a cloak of invisibility in the laboratory. The device works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space. The cloak consists of 10 fibreglass rings covered with copper elements and is classed as a "metamaterial" - an artificial composite that can be engineered to produce a desired change in the direction of electromagnetic waves. Like visible light waves, microwaves bounce off objects, making them apparent and creating a shadow. But at microwave frequencies, the detection has to be made by instruments rather than the naked eye.
Successes in the fields of Nanotechnology are poised to bring about so many changes in the ways we work and live. No? {X-Posted From}
