Refractive Index-Based Control of Hyperbolic Phonon-Polariton Propagation
Alireza Fali, Samuel T. White, Thomas G. Folland +7
Hyperbolic phonon polaritons (HPhPs) are generated when infrared photons couple to polar optic phonons in anisotropic media, confining long-wavelength light to nanoscale volumes. H…

Reconfigurable Mid-Infrared Hyperbolic Metasurfaces using Phase-Change Materials
Thomas G. Folland, Alireza Fali, Samuel T. White +7
Metasurfaces offer the potential to control light propagation at the nanoscale for applications in both free-space and surface-confined geometries. Existing metasurfaces frequently…
