Transcript Invisibility Cloaks

Invisibility Cloaks
They’re for more than just sneaking around
Hogwarts.
Scientists created metamaterials that trick
waves into thinking they have special
properties.
Metamaterials are structured materials
that are created by scientists altering
their geometry, not the atoms that make
up the substance.
Created from taking 1 cm2 of silk and
adding 10,000 gold spiral resonators.
The current design is
invisible to waves in the
Terahertz wavelength.
Silk is the first biocompatible
metamaterial.
This new technology has the potential to
be of great use in the medical industry
