A real Cloak of Invisibility.

"Titled 'Demonstration of an ultralow profile cloak for scattering suppression of a finite-length rod in free space,' their research, published in the New Journal of Physics, describes a cloak consisting of 66 µm-thick copper tape and 100 µm-thick flexible polycarbonate film which scatters and cancels out incoming waves."
“In principle this technique may be extended to visible frequencies; in fact metasurfaces are easier to realize than metamaterials in optics. However, the object size that can be efficiently cloaked with this method scales with the wavelength, so when applied to optical frequencies we may be able to efficiently stop the scattering of only micrometer-sized objects,” the research paper claims.
