Color Tuning by Spontaneous Propagation of Gap Surface Plasmons in Epsilon Near Zero Nano-Cavity
Giuseppe Emanuele Lio, Antonio Ferraro, Michele Giocondo +2
This work presents numerical and experimental results of plasmonic Metal-Insulator optical nano-cavities. The systems are composed of Silver as metal, polyvinylpyrrolidone or indiu…
Biomolecular sensing at the interface between chiral metasurfaces and hyperbolic metamaterials
Giovanna Palermo, Giuseppe E. Lio, Marco Esposito +6
In recent years significant efforts have been made to design and fabricate functional nanomaterials for biomedical applications based on the control of light matter interaction at…
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…
