title: Dirac dispersion in photonic hypercrystals.
abstract: Photonic hypercrystals--the recently introduced concept of artificial optical media that combines the properties of hyperbolic metamaterials and photonic crystals [E. Narimanov, Phys. Rev. X, 2014, 4, 041014]--can support Dirac cone dispersion at a finite frequency.
