Zero-index metamaterial based all-dielectric nanoantenna
Source abstract
Abstract
In this article, a highly directive all-dielectric zero-index metamaterial (ZIM) based nanoantenna has been proposed which has the ability to directionally transmit the radiation from an isotropic quantum emitter. The zero-index metamaterial (ZIM) used here, is basically a rods-in-air type photonic crystal, which exhibits zero-index behaviour owing to the existence of a Dirac-cone at the Gamma (Γ) point in its photonic band structure. The emitter is embedded inside the ZIM and the radiation pattern can be controlled by varying the shape and size of the array.
