How to make Invisible Objects

The Theory of Invisibility:--------


Invisibility is a state of which an object cannot be seen, and is a myth that has dated back to many fantasy and science fiction books, such as Harry Potter's cloak of invisibility, or Artemis Fowl's high-vibration suit. To have the ability to turn invisible would be a great advantage in almost all situations, for both government and everyday issues. In most of the traditional fantasy books, an invisible substance is something that either does not reflect light, or absorbs light (allows light to pass through it), although there are no naturally recurring objects that are 100% transparent.

However although it seems impossible, scientists have revealed they developing a new material, one that acts as a shawl of invisibility, much like in Harry Potter. This may seem far fetched but when you look at the evidence, it seems that in the distant future, this type of state maybe possible.

The key to that possibility is the development of increasingly complex metamaterials -- manmade composites engineered on a nano scale with properties entirely different to anything found in nature.
Doctor Ulf Leonhardt, a physicist at Scotland's St. Andrews University who has recently published two papers on the theory behind invisibility technology, said the key was developing a transparent material capable of bending light around an object concealed behind it.

The Yemeni professor was recently honored in Britain for his theory on the invisibility of objects. At the British Science Festival, Al-Omainey received the Isambard Kingdom Brunel Award, an award given annually to young engineers and scientists who exhibit outstanding communication skills when before a non-specialist audience.

31-year-old Dr. Akram Al-Omainey's award-winning research was on the “engineering cloak of invisibility,” a theory which suggests that human beings can be made invisible.
"My main research focus was on the influence of radio signals on the human body and vice-versa, which to the external spectator seems to be a straightforward and direct problem and solution equation. It is, however, a complex issue due to the realization that we humans are not only physiologically and psychologically complex: we are also one complicated electric machine, with each organ and blood vein carrying different properties,” he said.
