Instantaneous control of scattering from a time-modulated meta-atom

Time-modulation of material parameters is a powerful tool that enables ultimate control over scattered light. Proper description of scattering from time-modulated materials should be written rigorously in the time domain. This becomes possible if the properties of a single time-varying meta-atom are also considered in the time domain. In this talk we will present a theoretical model which describes a time-variant meta-atom and its interaction with an incident electromagnetic wave. Based on the developed theory, we will present several peculiar applications of time-varying meta-atoms, such as cancellation of scattering and shifting the frequency of the scattered wave.Peer reviewe
