An embodiment of the present invention provides a method of modeling electrostrictive effects and acoustic resonances in a tunable capacitor, comprising adjusting empirically the characteristic impedances and complex propagation constants to account for actual process variations in manufacturing of said tunable capacitor; adjusting empirically the characteristic impedances and complex propagation constants to account for end-effects in the directions transversal to the wave direction; and modeling the electrostrictive effect by dividing a BST layer of said tunable capacitor into thin layers or slices with each slice's thickness representing a small fraction of an acoustic wavelength and injecting at each junction between slices, an acoustic "current" proportional to the electrical current through said voltage tunable capacitor.
