Temporal multilayer structures for designing higher-order transfer functions using time-varying metamaterials
Davide Ramaccia, Andrea Alu, Alessandro Toscano +1
Temporal metamaterials are artificial materials whose electromagnetic properties change over time. In analogy with spatial media and metamaterials, where their properties change sm…

Temporal refraction and reflection in modulated mechanical metabeams: theory and physical observation
Shaoyun Wang, Nan Shao, Hui Chen +6
Wave reflection and refraction at a time interface follow different conservation laws compared to conventional scattering at a spatial interface. This study presents the experiment…
