The application, which could be made, is specific lens system for optical microscopes. This could focus on things as smaller in size as molecules. However, the holy grail of metamaterials has turn into rather invisibility screen. That provoked human being imagination from H.G. Well’s novel "Invisible Man" to today’s adventuring films of character Harry Potter.
American military is funding the research. The research is focused to create substances that could usher in a wholly future generation of stealth technology engineering. The metamaterial made by Zhang and his fellow scientist features a multi-layered fishnet construction. It is made of alternating layering substances of silver and magnesium fluoride. These materials are transparent throughout an extremely broad range of light orientations.
According to Zhang in the news published in Sunday Times, he said that in invisibility cloaks or protective covering materials, substances would move the direction of light waves totally around the thing just in a manner a river flows around a rock. An observer taking a view of the cloaked thing would then see light from its back and it seems to be disappeared.
