Abstract
An embodiment of the present invention provides a method, comprising reducing the losses due to electro-mechanical coupling and improving Q in a multilayered capacitor by placing a first capacitor layer adjacent at least one additional capacitor layer and sharing a common electrode in between the two such that the acoustic vibration of the first layer is coupled to an anti-phase acoustic vibration of the at least one additional layer.
