Researchers have succeeded in controlling “hyperbolic polaritons” for the first time – in a van der Waals heterostructure made of monolayer graphene on hexagonal boron nitride (hBN). They were able to do this by making use of the surface plasmon polaritons in graphene and the hyperbolic phonon polaritons in hBN to create hybrid hyperbolic plasmon-phonon polaritons in graphene/hBN “metastructures”. The work could be important for developing advanced photonics devices, including those made from subdiffractional optical and negative refraction index materials………….
