'Cloak of Invisibility' Realized in Theory

Researchers at Toyama Prefectural University and other institutions announced that they theoretically formulated a "perfect invisible cloak."
The invisible cloak generates no reflection or phase delay at all even when an electromagnetic wave passes through it. It was developed with the use of an artificial dielectric material called "left-handed metamaterial," which has a negative refractive index n. It can be said that the researchers created a sort of blueprint of the perfect invisible cloak. |
