We demonstrate the possibility to tune the permittivity of thin films of strontium titanate by means of an electric field. We propose to deposit on top of such films a metallic metamaterial structure designed to resonate in the terahertz range. The amplitude and frequency of this resonance will then be tunable by applying a bias.
