OECD category: Condensed matter physics (including formerly solid state physics, supercond.)

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.
