Time-switched metastructures: analysis and design of the anomalous radiative phenomena at time-interfaces
In the last few years, the temporal counterpart of spatial interfaces, named temporal interfaces, has been deeply investigated to model, validate, and exploit several novel anomalous wave phenomena in time-domain. Reflection and transmission, accompanied by frequency conversion, always take place at a temporal interface between two different unbounded media, but, recently, temporal interfaces triggered by the effective media parameters experienced by guided waves have been proposed. In this contribution, the recent findings on boundary-induced temporal interfaces are presented, considering two different guiding structures capable to radiate a continuous spatio-temporal spectrum in different directions and a highly confined beam radiated in end-fire direction, respectively.
