Abstract
The invention discloses a tuneable resonator () with a substrate layer (), which substrate layer supports a structure with a first electrode (). In connection to the first electrode there is arranged a layer () of a material which can be brought to resonate. The resonator further comprises a second electrode () arranged in connection to said material which can be brought to resonate, and the material which can be brought to resonate is a ferroelectric material. The ferroelectric material is brought into resonance by applying an electrical field (DC, AC) between the first and the second electrode, the tuning being achieved by varying the electrical field.
