In this talk, we discuss our recent results in the area of active and tunable metasurfaces, including the possibility of inducing hyperbolic plasmons and topological transitions on graphene-based metasurfaces, the realization of cloaks and planar lenses based on parity-time symmetric metasurfaces, and of isolators and non-reciprocal components based on time-varying metasurfaces.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
