Populating the large-wavevector realm: Bloch volume plasmon polaritons in hyperbolic and extremely anisotropic metamaterials

Abstract

Optics of hyperbolic metamaterials is revisited in terms of large-wavevector waves, evanescent in isotropic media but propagating in presence of extreme anisotropy. Identifying the physical nature of these waves as Bloch volume plasmon polaritons, we derive their existence conditions and outline the strategy for tailoring their properties in multiscale metamaterials.
