Abstract:
1. A multilayered capacitor, comprising: a plurality of voltage tunable dielectric layers including a first voltage tunable dielectric layer with a first density and a first thickness and a second voltage tunable dielectric layer with a second density and a second thickness; and one or more electrodes including a common electrode positioned between and shared by the first and second voltage tunable dielectric layers, wherein the first and second densities and thicknesses are selected so that a first vibration of said multilayered tunable capacitor caused by an application of a substantially orthogonal RF signal is reduced by a second electro-mechanical vibration generated by one or more bias voltages applied to the first and second tunable dielectric layers via the common electrode, wherein the substantially orthogonal RF signal is applied without applying a substantially lateral RF signal along a length of the common electrode, wherein the second electro-mechanical vibration has a phase that differs from a phase of the first electro-mechanical vibration, wherein the application of the one or more bias voltages in conjunction with the first and second densities and the first and second thicknesses of the first and second dielectric layers enable generating the first and second electro-mechanical vibrations that substantially cancel each other, and wherein the one or more bias voltages are applied to enable a number of the plurality of voltage tunable dielectric layers that are positively biased to equal a number of the plurality of voltage tunable dielectric layers that are negatively biased.
