  "abstract": "We have implemented and investigated the tunable hyperbolic response in heterostructures comprised of a monolayer graphene deposited on hexagonal boron nitride (G-hBN) slabs. Electrostatic gating of the graphene layer enables electronic tunability of phonon polaritonic properties of hBN: a layered material with well-documented hyperbolic response in the mid-infrared (mid-IR) frequencies. The tunability originates from the hybridization of surface plasmon polaritons in graphene to hyperbolic phonon polaritons in hBN: an effect that we examined via nano-IR imaging and spectroscopy. The hybrid polaritons possess combined virtues from plasmons in graphene and phonon polaritons in hBN. Therefore, G-hBN structures fulfill the definition of the electromagnetic metamaterial since the attained property of these devices is not revealed by its constituent elements. Our results uncover a practical approach for realization of agile nano-photonic metamaterials by exploiting the interaction of distinct types of polaritonic modes hosted by different constituent layers of van der Waals heterostructures.",
