Abstract
Although recent advances in metamaterials and metasurfaces have dramatically extended their capabilities, the impact and applicability of such engineered materials is still hindered by several physical limitations and bounds, especially in relation to bandwidth and size restrictions. Lately the notion of dynamic spatio-temporal modulation of material properties has been the subject of growing interest and research efforts, opening a new landscape of opportunities, and providing new means to go beyond various conventional limits in photonic systems. Here, we provide an overview of our recent work on overcoming the bandwidth restrictions for open resonators, scatterers, and metasurfaces. We also discuss the exciting possibility of enabling novel, anomalous, nonlinear wave dynamics through judicious modulation of material properties in both space and time.
