The phenomenon of zero refractive index, exhibited by ZIMs, has proven highly useful, especially in the fields of waveguiding and optics. Silicon carbide, classified as a polaritonic material, ...

In a medium with a refractive index of zero n = 0, the effective wavelength becomes infinite, λ = 2πc/ωn→∞, and the spatial phase distribution of a propagating wave becomes uniform over the entire ...

In 2015, researchers developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase of light could be stretched infinitely long. The metamaterial represented a new ...

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 ...

In 2015, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase ...

(Nanowerk News) In 2015, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed the first on-chip metamaterial with a refractive index of zero, meaning ...
