metamaterial membranes = invisibility cloak?

A new material that could be used to create a real-life Harry Potter-style “invisibility cloak” has been designed by British scientists.

The material, viagra order called “Metaflex”, side effects may in future provide a way of manufacturing fabrics that manipulate light. Metamaterials have already been developed that bend and channel light to render objects invisible at longer wavelengths.

Scientists at the University of St Andrews in Scotland have produced flexible metamaterial “membranes” using a new technique that frees the meta-atoms from the hard surface they are constructed on.

Metaflex can operate at wavelengths of around 620 nanometres, stomach within the visible light region.

Stacking the membranes together could produce a flexible “smart fabric” that may provide the basis of an invisibility cloak, the scientists believe. - [source]
