LINEAR AND NONLINEAR SCATTERING FROM ENGINEERED NANODEVICES

The main research topic deals with describing linear and nonlinear scattering from metallic, dielectric and phase transition nanoparticles. In the first part of the research activity switching from the dielectric to the metallic phase is exploited to change the linear scattering of linear wire antennas. By exploiting VO2 metal-insulator phase transitions we intend to demonstrate how to control the scattering cross section of optical nanoantennas.
In the second part of the research activity we intend to analyse harmonic generation driven by Mie resonances in single or coupled resonators.
The activity entails both numerical modelling along with setting up nonlinear microscopy experiments and to drive the theoretical findings into the design of devices for optical sensing at the nanoscale.
