Abstract:

In this talk, I discuss our recent research activity in electromagnetics, optics, photonics, and acoustics, showing how suitably tailored meta-atoms and their arrangements of them open exciting avenues to realize new phenomena for light, radio-waves, and sound. I discuss opportunities to tailor the impinging electromagnetic waves in robust and efficient ways, to largely break Lorentz reciprocity and realize isolation without the need for magnetic bias, based on broken time-reversal symmetry induced by mechanical motion, spatio-temporal modulation, and/or nonlinearities. I also discuss how broken symmetries in space and space-time can open the opportunity to induce topological order in metamaterials. In the talk, I will also discuss the impact of these concepts from basic science to practical technologies, from classical waves to quantum phenomena.
