Hyper Resolute Ultra thin Low Cost All-Dielectric Broadband Achromatic Metalenses
Giuseppe Emanuele Lio, Antonio Ferraro, Tiziana Ritacco +4
Metalenses offer the ground-breaking opportunity to realize highly performing low-weight, flat and ultrathin, optical elements which substantially reduce size and complexity of ima…
Hyper Resolution Two Photon Direct Laser Writing using ENZ Nano-Cavity
Giuseppe Emanuele Lio, Tiziana Ritacco, Antonio Ferraro +3
A novel technique is reported to improve the resolution of two-photon direct laser writing lithography. Thanks to the high collimation enabled by extraordinary (…
Numerical modeling of active thermo-plasmonics experiments
Giuseppe E. Lio, Giovanna Palermo, Antonio De Luca +1
In this paper, we present a simple and robust numerical method able to predict, with high accuracy, the photo-thermal effects occurring for a gold nanoparticles arrangement under e…
A numerical ellipsometric analysis (NEA) of nanoscale layered systems
Giuseppe Emanuele Lio, Giovanna Palermo, Roberto Caputo +1
A simple and robust method able to predict, with high accuracy, the optical properties of single and multi-layer nanostructures is presented. The method exploits a COMSOL Multiphys…
