Abstract

Metamaterials are artificial materials with properties well beyond what offered by nature, providing unprecedented opportunities to tailor and enhance the control of waves. In this talk, I discuss our recent activity in electromagnetics, nano-optics and acoustics, showing how suitably tailored meta-atoms and their arrangements open exciting venues for scattering manipulation and non-invasive sensing, metasurfaces for wavefront manipulation and analog computing, nonreciprocity and topological phenomena induced by spatio-temporal modulation, opto-mechanical phenomena or nonlinearities, and giant nonlinear and quantum effects at subwavelength scales. Physical insights into the underlying physics and new technology based on these concepts will be presented and discussed.
