High temperature superconductors (HCTS) are one of the most promising candidatesfor active and tunable metamaterials in the terahertz range. In this work we demonstratethe restoring of the plasmonic regime and a good tunability of plasmonic resonances up to 3 THzacross the superconducting transition of YBa2Cu3O7 lms. A similar behavior can be obtainedin other HCTS systems, showing an universal plasmonic response for superconducting materials.
