Invisibility Cloak-Reality or Science fiction

Invisibility technology, or gadgets that make people invisible and blend with environs, has caught the interest of scientists for years. According to the journal “Advanced Optical Materials,” scientists have created artificial nanostructures called metamaterials that can ‘bend light.’ It was definitely able to assemble a bigger swath of multilayer 3-D metamaterial functioning in the visible spectral region. They performed this achievement by applying nanotransfer printing, which would have the potential to be programmed and vary overall surrounding refractive index required for regulating light propagation.
