Enhanced Nonlinear Refractive Index in ε-Near-Zero Materials.
New propagation regimes for light arise from the ability to tune the dielectric permittivity to extremely low values. Here, we demonstrate a universal approach based on the low linear permittivity values attained in the ε-near-zero (ENZ) regime for enhancing the nonlinear refractive index, which enables remarkable light-induced changes of the material properties. Experiments performed on Al-dop...
متن کاملMicrostrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...
متن کاملNear - zero refractive index photonics
The control and manipulation of light on the nanoscale — the primary aim of nanophotonics — is of fundamental scientific interest and plays a key role in telecommunication technologies and energy management. Yet, because light–matter interactions are usually weak and hard to confine, they often need to be assisted by the use of suitably designed macroscopic media. For instance, the use of caref...
متن کاملPhotonic crystals and negative refractive index materials
We review the research of our group on propagation of electromagnetic waves in photonic crystals (PCs) and micrometer scale left-handed materials (LHMs). The main topics that we focus on regarding PCs are the modification of the spontaneous emission rate of sources embedded into them, their ability to produce beams with high directionality and their negative refraction and focusing properties, ...
متن کاملDirac directional emission in anisotropic zero refractive index photonic crystals
A certain class of photonic crystals with conical dispersion is known to behave as isotropic zero-refractive-index medium. However, the discrete building blocks in such photonic crystals are limited to construct multidirectional devices, even for high-symmetric photonic crystals. Here, we show multidirectional emission from low-symmetric photonic crystals with semi-Dirac dispersion at the zone ...
