First 3D Cloaking Effect Demonstrated

Holy Klingon! Mr Spock what will they think if next?

Alu and his fellow researchers managed to achieve the 3D cloaking using “plasmonic metamaterials,” synthetic materials consisting of alternating pieces of metal and insulation that have ultra-small differences in shape, smaller than than the wavelength of light.

When light hits non-transparent 3D objects, it scatters, and some of it bounces back to our eyes, allowing us to see them.

When light and energy of other wavelengths strike plasmonic metamerials, though, they act as though they were passing through glass rather than an opaque, solid material. That’s because the tiny features of the plasmonic metematerials surpress the natural “scattering effect” that occurs when energy, like light, strikes an object.

“The field [of energy] goes through the object and the cloak, as if they were made of the same transparent material (think of glass),” Alu told TPM via email.

Plasmonic Metamaterials,? Sounds expensive.
