The SAW device with the electroinduced controllable structure was investigated theoretically and experimentally. The innovative SAW device on a LiTaO3 single crystal with the volume existed and controllable domain structure was proposed. The parameters of the electroinduced structure as well as the acoustic wave interaction have ability to control. The theoretical and experimental results of the acoustic wave interaction in the ferroelectric waveguide with the electroinduced periodical structures were discussed.
Keywords: surface acoustic wave (SAW), ferroelectric domain, phonic crystal, acoustic metamaterials.
