The Invisible Man

United States Scientists are closer to developing materials that could make people invisible. Researchers @ the University of California developed a material that can bend light around "3D" ( a three-dimensional form or appearance) objects making them "disappear". The materials made are not natural. Created on a nano scale, measured in billionths of a metre, to make invisibility cloaks large enough to hide people which could endues stealth operations. Scientists led by: Professor Xiang Zhang, findings were published Nature and Science Journal. The light-bending effect relies on reversing refraction, the effect that makes a straw placed in water appear bent. Previous efforts have shown this negative refraction effect using a microwave. In order to have what is referred to as the 'Harry Potter' effect, you just need to find the right materials for the visible wavelengths. Different teams led by Zhang made objects made of so-called "metamaterials—artificial structures" with features smaller than the wavelength of light that give the materials their unusual properties. One approach used nanometre-scale stacks of silver and magnesium fluoride in a "fishnet" structure, while another made use of nanowires made of silver. Light is neither absorbed nor reflected by the objects, passing "like water flowing around a rock". As a result only the light from behind the objects can be seen. Clo The fine structure of the material gives it light These bending abilities could be used to make better microscopes, allowing images of far smaller objects been seen.
