Hyperbolic metamaterials based on multilayer graphene structures

Iorsh, Ivan; Mukhin, Ivan S; Shadrivov, Ilya; Belov, Pavel A; Kivshar, Yuri

Description

We propose metamaterials for THz frequencies based on multilayer graphene structures. We calculate the dielectric permittivity tensor of the effective nonlocal medium with a periodic stack of graphene layers and demonstrate that tuning from elliptic to hyperbolic dispersion can be achieved with an external gate voltage. We reveal that such graphene structures can demonstrate a giant Purcell effect that can be used for boosting the THz emission in semiconductor devices. Tunability of these...[Show more]
