Investigation of a Solid-State Tuning Behavior in Lithium Niobate.

Electric field-based frequency tuning of acoustic resonators at the material level may provide an enabling technology for building complex tunable filters. Tunable acoustic resonators were fabricated in thin plates (h/ λ  ∼  0.05 ) of X-cut lithium niobate (LiNbO) (90°, 90°, ψ = 170 ).
