Abstract
A voltage-controllable capacitive device includes a first dielectric material and at least one further dielectric material. At least the permittivity of the first dielectric material is DC voltage-dependent. A voltage dependence of the permittivity of the first dielectric material is different from a voltage dependence of the permittivity of the further dielectric material. The device further includes at least one voltage providing element for providing a DC voltage to the first dielectric material.
