Abstract
An apparatus for introducing electromagnetic perturbation into a target device includes a piezoelectric transducer configured to deflect in response to an applied voltage and a perturber configured to deflect in response to deflection of the piezoelectric transducer. The deflection of the perturber causes electromagnetic perturbation, and in some cases a phase shift, in the target device. The electromagnetic perturbation may also be used to tune microwave devices such as filters, resonators, and oscillators.
