Floquet topological insulators are materials with topological phases that originate from tailored time-dependent perturbations of their crystal structure. These materials have been proved to feature highly unusual electron conduction properties. In recent years, there has been significant interest in exploring analogous features for electromagnetic waves using tailored metamaterials, which promise exciting opportunities for a wide range of applications, including the development of wireless communication, radar and quantum technology.
