In this work, by using an extraordinary transmission metamaterial prism and taking advantage of its inherent dispersive behavior, the feasibility of manufacturing a demultiplexer/multiplexer or even a spectrogram analyzer at millimeter-waves is shown. Depending on the incoming beam frequency, the outgoing beam suffers in a wedge-shaped configuration a different deflection (governed by Snell's law). Since the frequency dependent index of refraction of this metamaterial can go from negative values to almost zero for the first propagation band (cut-off regime) and also be positive for the second propagation mode (non-cut-off regime), different negative and positive outgoing angles can be obtained and then, diverse paths for each frequency, as the Fresnel zone experimental results confirm.read more

Fishnet metamaterial from an equivalent circuit perspective
TL;DR: In this paper, an equivalent circuit for the double-fishnet metamaterial was proposed and all lumped elements were inferred from the interpretation of the electric and magnetic fields as well as the surface currents generated when the structure is excited with a normally incident plane wave.
Polarization-tunable negative or positive refraction in self-complementariness-base-d extraordinary transmission prism

Connection between extraordinary transmission and negative refraction in a prism of stacked sub-wavelength hole arrays
TL;DR: In this paper, a prism engineered by stacking sub-wavelength hole arrays is shown as a route to negative refraction in any frequency range, which is intimately linked to the extraordinary transmission resonance of subwavelength holes arrays.

TL;DR: In this article, the optical properties of submicrometre cylindrical cavities in metallic films were explored and it was shown that arrays of such holes display highly unusual zero-order transmission spectra at wavelengths larger than the array period, beyond which no diffraction occurs.

TL;DR: A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range, which results from the plasmon resonance in the pairs of nanorod for both the electric and the magnetic components of light.
