From surface to volume plasmons in hyperbolic metamaterials: General existence conditions for bulk high- k waves in metal-dielectric and graphene-dielectric multilayers
Physical Review B, 2014.
We theoretically investigate general existence conditions for broadband bulk large-wavevector (high-k) propagating waves (such as volume plasmon polaritons in hyperbolic metamaterials) in subwavelength periodic multilayer structures. Describing the elementary excitation in the unit cell of the structure by a generalized resonance pole o...More
