The recent research progress on tunable metamaterials is reviewed in the paper. Some classic kinds of tunable metamaterials design, such as the liquid crystals based, ferrites based, superconductor based, varactor loaded, capacitor loaded, MEMS based, and the mechanical tunable metamaterials are introduced, respectively. We also compare the advantageous and deficiencies of the reported tunable metamaterials in every aspect from the fabrications and potential applications.
