A conformal scheme to design broadband polarization-independent invisibility cloak with wide angles of illumination

Metamaterials, a kind of artificially structured materials with exotic optical properties, offer a route to manipulate electromagnetic waves in an unprecedented way. One of the most well-known applications of metamaterials is the design of invisibility cloaks, where judiciously designed metamaterial...

description Metamaterials, a kind of artificially structured materials with exotic optical properties, offer a route to manipulate electromagnetic waves in an unprecedented way. One of the most well-known applications of metamaterials is the design of invisibility cloaks, where judiciously designed metamaterial structures can guide electromagnetic waves smoothly around a certain region, rendering any object placed inside this region invisible to outside detector. Although there are several experimental demonstrations of metamaterial cloaks at microwave and optical frequencies, these cloaks normally work for a single polarization.
