Abstract
A tunable dielectric metamaterial device for radar sensing comprises at least one metamaterial layer a plurality of electrically conductive electrodes and a plurality of electrically conductive control lines. The metamaterial layer includes a plurality of dielectric resonators comprising tunable material, wherein at least one electromagnetic property of the tunable material varies with an externally controllable electric field applied to it. Two distinct electrically conductive electrodes each are arranged in a spaced manner at any one of the dielectric resonators to cover the dielectric resonator. The electrically conductive control lines are configured for controlling the electric field to be applied to the tunable material, wherein each electrically conductive line is electrically connected to an electrically conductive electrode. For at least two dielectric resonators, the electrically conductive electrodes that are arranged in the same layer to cover the at least two dielectric resonators are distinct from each other.
