“…Examples of recent developments include, but are not limited to, the rigorous research on High Intensity Focus Ultrasound 1,2 and its clinical aspects 3 including ultrasound applications for drug delivery, 4 medical ultrasonic transducers for high frequency operation, 5 and others. In this respect, research on periodically poled ultrasonic transducers is connected to ceramic materials with inversely poled ferroelectric domains, 6,7 their efficiency of acoustoelectric transduction in bulk, [8][9][10] and two-dimensional [11][12][13] acoustic superlattices. Other types of promising vibrators are multi-layer transducers, 5,14 which were invented more than 2 decades back.…”

A split-mode ultrasonic transducer is investigated in both theory and experiment. This transducer is a two-dimensional structure of periodically poled domains in a ferroelectric wafer with free surfaces. The acoustic vibrations are excited by a radio frequency electric current applied along the length of the wafer, which allows the basal-plane surfaces to be free of metal coatings and thus ready for further biomedical applications. A specific physical property of this transducer consists of the multiple acousto-electric resonances, which occur due to an acoustic mode split when the acoustic half-wavelength is equal to the domain length. Possible applications include ultrasonic generation and detection at the micro-scale, intravascular sonification and visualization, ultrasound therapy of localized small areas such as the eye, biomedical applications for cell cultures, and traditional nondestructive testing including bones and tissues. A potential use of a non-metallized wafer is a therapeutic application with double action that is both ultrasound itself and an electric field over the wafer. The experimental measurements and theoretical calculations are in good agreement.

“…This fact can represent a strong limitation for the experimental techniques used to prepare PPLN structures. As a matter of fact, periodically poled structures are usually prepared by the electric-field poling technique by applying an electric field either during the material growth (about 0.4 V/cm) or after that, even at room temperature [7,8]. In this case, when small periods are required complications can arise from such very narrow electrode deposition.…”

“…Ultrasound is managed through the interaction of a SAW with structures whose parameters can be controlled by an external action. 8) There are different methods for the management of induced domain structures, [9][10][11][12][13][14][15][16][17] which may be a laser beam, 18) a magnetic field, or a mechanical action. However, operation and flexibility are generally realized by an electroinduced method of formation of the anisotropy in a volume of crystals, because in these artificial structures, ultrasound band gaps, for example, can be achieved.…”

In recent years, there has been great interest in developing different kinds of phononic crystals (PCs) with advanced ultrasound properties. In this study, we examined the possibility of creating a periodic domain structure controlled by an external electric field. The electric field was induced using crossed electrodes on the surface of a LiTaO3 single crystal. We investigated the domain formation process, in which the external electric field was smaller than the coercive electric field, and spontaneous polarization is not inverted. We proposed a new type of surface acoustic wave device and studied the parameters of interaction of a low-velocity shear horizontal acoustic wave with an electroinduced domain structure. This new kind of acoustic device allows the study of various ultrasound effects and the development of advanced controllable acoustoelectronic devices.
