Negative refraction in natural ferromagnetic metals
Negative refraction natural ferromagnetic metals
2010/11/23
It is generally believed that Veselago’s criterion for negative refraction cannot be fulfilled in natural materials. However, considering imaginary parts of the permittivity (") and permeability(μ) an...
Broad angle and frequency tunable photoniccrystal-polarization beam splitterbased on negative refraction:Transition from right-handedto left-handed medium

A new design of a broad angle photonic crystal polarization beam splitter (PhC-PBS) with
frequency tunable index of refraction, i.e. varying from positive to negative, is presented.
Designed PhC-PBS...
Low-loss negative refraction by laser induced magneto-electric cross-coupling
Low-loss negative refraction laser magneto-electric cross-coupling

We discuss the feasibility of negative refraction with reduced absorption in coherently driven atomic media. Coherent coupling of an electric and a magnetic dipole transition by laser fields induces m...
Negative Refraction Using Frequency-Tuned Oxide Multilayer Structure
Frequency-Tuned Oxide Multilayer Structure
2008/10/31
An oxide-based multilayer structure was proposed to realize negative refraction. The multilayer composes of alternative layers having negative permittivity and negative permeability, respectively. In ...
All-Angle Negative Refraction for Surface Plasmon Waves Using a Metal-Dielectric-Metal Structure
All-Angle Negative Refraction Surface Plasmon Wave Metal-Dielectric-Metal Structure
2015/8/11
We show that a metal-dielectric-metal structure can function as a negative refraction lens for surface plasmon waves on a metal surface. The structure is uniform with respect to a plane of incidence a...

All-angle negative refraction evanescent wave one-dimensional metallodielectric photonic crystals
2015/8/11
The authors numerically demonstrate all-angle negative refraction for propagating waves, as well as evanescent wave amplifications, using a one-dimensional photonic crystal consisting of metal-d...
