Epsilon-near-zero (ENZ) materials are materials that have a spectral region where the permittivity is below zero. This leads to unconventional optical behaviour, ranging from light propagation through arbitrary…
Metasurfaces based on epsilon-near-zero materials show very strong nonlinear responses and allow coupling of light to optical modes in the epsilon-near-zero thin film that are otherwise not accessible at normal…
Our recent APL Photonics paper on flexible epsilon-near-zero metamaterials has been highlighted in the News & Views section of the July Issue of Nature Photonics. Congratulations to everyone involved.
Epsilon-near-zero materials promise non-linear optical enhancement, light transport through arbitrary channels, wave-front shaping and control over optical emission. Typically implemented using either naturally…
