Infrared light scattering and emission from epsilon near-zero hyperbolic phonon-polaritons in two-dimensional crystals
Flavio Henrique Feres, Martin Bearzatto, Adrien Debacq +24
This work presents the near-field super-scattering and the near-field thermal emission from 2D hyperbolic crystals as general optical phenomena that link near-field nanophotonics t…

Group velocity modulation and wavelength tuning of phonon-polaritons by engineering dielectric-metallic substrates
Flávio H. Feres, Rafael A. Mayer, Ingrid D. Barcelos +2
In analogy to the observed for single plasmon-polaritons, we show that subdiffractional hyperbolic phonon-polariton (HP2) modes confined in hexagonal boron nitride (hBN) nanocrysta…
