Description
Summary:Temporal metamaterials, which have constitutive parameters that vary with time, have become an area of significant research interest due to their potential to enhance light-matter interactions and create devices with unique capabilities. Here, we will review some recent developments in this exciting field, with a particular focus on short-pulsed metamaterials, which are characterized by a dielectric permittivity waveform that is much shorter in duration than the characteristic wave-dynamical timescale. We will also discuss temporal anisotropic metamaterials, which exhibit changes in their electromagnetic response over time, transitioning from isotropic to anisotropic and vice versa.
