Hybridized hyperbolic surface phonon polaritons at α-MoO3 and polar dielectric interfaces
Qing Zhang, Qingdong Ou, Guangwei Hu +5
Surface phonon polaritons (SPhPs) in polar dielectrics offer new opportunities for infrared nanophotonics due to sub-diffraction confinement with low optical losses. Though the pol…
