Light can interact with nanostructured materials giving rise to several physical phenomena, including enhanced electric fields, generation of high energy carriers and heat dissipation. These effects can be manipulated by engineering such materials into optical metasurfaces where the shape, material and arrangement of the meta-atoms, the metasurface building blocks, can be modified depending on the application. This talk reports recent results where nanoscale optical metasurfaces are utilized in diverse systems, targeting extreme electromagnetic energy focusing, light rectification or steam generation.

Abstract
Light can interact with nanostructured materials giving rise to several physical phenomena, including enhanced electric fields, generation of high energy carriers and heat dissipation. These effects can be manipulated by engineering such materials into optical metasurfaces where the shape, material and arrangement of the meta-atoms, the metasurface building blocks, can be modified depending on the application. This talk reports recent results where nanoscale optical metasurfaces are utilized in diverse systems, targeting extreme electromagnetic energy focusing, light rectification or steam generation.File in questo prodotto:
