Figure 1: Analytical study of one-dimensional chains of resonant point scatterers. Starting from this unit cell that creates the single negative property, we build two new configurations just by ...

The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...
