In this paper we review some metasurfaces with negative values of effective refractive index,
as scaffolds for a new generation of surface plasmon polariton-based biological or chemical …

Although metasurfaces have shown great potential for manipulating light, most previously
realized meta-devices suffer from uncontrolled angular dispersions, making them …

We experimentally demonstrate a low-loss multilayered metamaterial exhibiting a double-
negative refractive index in the visible spectral range. To this end, we exploit a second-order …

We study experimentally the nonlinear properties of fishnet metamaterials infiltrated with
nematic liquid crystals and find that moderate laser powers result in significant changes of …

We analyze numerically the optical response and effective macroscopic parameters of
fishnet metamaterials infiltrated with a nematic liquid crystal. We show that even a small …

We demonstrate for the first time a fast and easy nanoimprint lithography (NIL) based
stacking process of negative index structures like fishnet and Swiss-cross metamaterials …

Negative index metamaterials have revolutionized the field of photonics because of their
unconventional electromagnetic properties absent in naturally occurring materials. It …

We explore the nanoscale colloidal self-assembly and self-alignment in liquid crystals. We
use model particles with controlled shapes and sizes, including quantum dots and rods and …

The tunable optical response of elliptical nanohole arrays penetrating through metal–phase
change material–metal (Au− Ge 2 Sb 1 Te 4− Au) films is numerically investigated using the …

In standard quantum mechanics, complex numbers are used to describe the wavefunction.
Although this has so far proven sufficient to predict experimental results, there is no …
