Abstract

High‐Q SAW grating resonators with tunabilities approaching 1% are possible on certain ferroelectric‐ferroelastic crystals such as Gd₂(MoO₄)₃. The resonant frequency is tuned by electronically varying the width of a small domain with different acoustic velocity within the resonator cavity. Experimental results at ∼92.6 MHz are presented.
