Collective near-field coupling and nonlocal phenomena in infrared-phononic metasurfaces for nano-light canalization
Phenomena such as polariton canalization and hyperlensing can be found at the transition from hyperbolic to elliptical dispersion. Here, the authors investigate this transition using hyperspectral infrared nanoimaging of polaritons in a grating of hexagonal boron nitride nanoribbons.
