'Invisibility' Materials Could Perform Calculations As Well
According to a latest research, scientists are of the view that the material which is said to be used in the Harry Potter's invisibility cloak can also perform advanced mathematical calculations, which are usually done by computers.
It has be proposed by an international team of researchers that the so called metamaterials, which are known to alter the properties of light waves in order to make an object invisible, are also capable of performing several mathematical operations.
Although the scientists have not been able to design the cloak properly as yet, but the work they are doing shows the mathematical basis for a new technology.
It is assumed by the scientists that this mathematical basis would be able to dramatically speed up the calculations, particularly those, which are used in image processing.
The above study has been published in this week's journal science, as per researchers. Until now the scientists were only using the metamaterials for blending the light around objects, to make them invisible at certain wavelengths.
But, according to Nader Engheta, who is a professor of electrical engineering at the University of Pennsylvania and co-author of the paper, the metamaterials could change the shape of an incoming light wave in ways that have the same effect as performing calculations on a computer.
