Launching of hyperbolic phonon-polaritons in h-BN slabs by resonant metal plasmonic antennas
Momentum mismatch prevents efficient coupling between free space photons and hyperbolic phonon polaritons. The authors show, using far-field infrared spectroscopy, infrared nanoimaging and numerical simulations, that resonant metallic antennas can efficiently launch hyperbolic phonon polaritons in t...
