Reconfigurable periodic structures and metamaterials: Enabling technologies, design, and applications from microwave to terahertz

In this presentation we will review our recent activity related to the dynamic reconfiguration of periodic structures and their application. Different reconfigurable periodic `meta' transmission lines, reconfigurable uniform and a-periodic metasurfaces, will be discussed together with their applications. The proposed concepts are implemented at various frequencies from microwave to terahertz, using different technologies including semiconductors diodes, metal MicroElectroMechanical systems (metal-MEMS), Graphene, and dielectric electro-active polymers (DEAP).
