TLDR
In this paper, the authors review some of the recent developments in the field of hyperbolic dispersion of metamaterials and their applications in a variety of phenomena, from spontaneous emission to light propagation and scattering.Abstract:
Metamaterials with hyperbolic dispersion (where two eigenvalues of the dielectric permittivity tensor have opposite signs) exhibit a broad bandwidth singularity in the photonic density of states, with resulting manifestations in a variety of phenomena, from spontaneous emission to light propagation and scattering. In this tutorial, I will review some of the recent developments in this field.read more

Tunable THz generation and enhanced nonlinear effects with active and passive graphene hyperbolic metamaterials
TL;DR: In this article, a new patterned graphene hyperbolic metamaterial (GHMM) was proposed to enhance the third harmonic generation (THG) due to the field enhancement at the resonance as well as the supported slow-light response that fosters strong light-matter interaction.

Photonic Crystals: Molding the Flow of Light
TL;DR: In this paper, the authors developed the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory, and investigated the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions.

On the Surface States Associated with a Periodic Potential
TL;DR: In this article, the wave functions and energy levels associated with a finite one-dimensional periodic potential field are investigated and the surface levels appear only at lattice constants so small that the boundary curves for the allowed energy bands have crossed.
