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

An Acoustic Hyperlens with Negative Direction Based on Double Split Hollow Sphere
Jung Sik Choi,Gil Ho Yoon +1 more
TL;DR: In this paper, a new acoustic negative-refraction metamaterial that utilizes a synthesized double split hollow sphere (DSHS) for its unit cell was developed, which is based on the same idea as the one described in this paper.

Imaging beyond the surface region: Probing hidden materials via atomic force microscopy
Amir Farokh Payam,Ali Passian +1 more
TL;DR: Subsurface imaging is possible under certain physical, chemical, electrical, and thermal gradients present in the material as discussed by the authors , but high-resolution subsurface imaging remains a nanometrology challenge due to electromagnetic and acoustic dispersion and diffraction.

First-principles study of the optical properties of BaMoO3/SrHfO3 hyperbolic metamaterials
Jonathan Gjerde,R. A. Jishi +1 more
TL;DR: In this paper , the authors use density functional theory to investigate BaMoO3-SrHfO3 metamaterials and predict that these are hyperbolic throughout the visible range and have the potential to mitigate many of the shortcomings of their constituent parts.

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.

Optical Hyperlens: Far-field imaging beyond the diffraction limit.
TL;DR: In this article, an approach to far-field optical imaging beyond the diffraction limit is proposed, which allows image magnification, is robust with respect to material losses and can be fabricated by adapting existing metamaterial technologies in a cylindrical geometry.

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.

TL;DR: A comparatively low-loss, three-dimensional, all-semiconductor metamaterial that exhibits negative refraction for all incidence angles in the long-wave infrared region and requires only an anisotropic dielectric function with a single resonance is demonstrated.
