High Transmission Acoustic Focusing by Impedance-Matched Acoustic Meta-Surfaces. WebThese ultrasonic piezo elements, also called atomizing transducers or piezo atomizers, work by creating a vibration mechanical response to an electrical input. The acoustic impedance matching layer is designed by equating the acoustic parameters to the transmission line parameters and connecting them with the acoustic ports of the KLM model as shown in Figure 12 (Yang et al., 2020). Due to the high temperature of densification and annealing during the preparation of piezoelectric film materials, the preparation of piezoelectric films and the production of transducers cannot be completely compatible. doi:10.1016/j.sna.2010.08.020, Leedom, D.

A., and Matthaei, G. L. (1970). Ferroelectrics, Frequency Control. This paper presents a finite element model for a 4 MHz ultrasonic transducer excited by a spike signal in pulse-echo mode. Therefore, we usually prefer to select the method by adding a matching layer to the piezoelectric material or lens surface for acoustic impedance matching in UHF. In the low-frequency range, epoxy can be considered to prepare a lens (Cannata et al., 2003), the epoxy lens is easy to mold and the prepared lens surface is smooth. Subsequently, based on these two methods, many new preparation methods have been introduced through process improvement. The preparation process requires a lot of time and effort, and with the further increase of the center frequency, the degree of difficulty may be more than a simple linear increase, so to increase the upper limit of UHF ultrasonic transducers, new materials are needed to provide the feasibility of extremely low thickness control. Editors W. P. Mason, and R. N. Thurston (Academic Press), 221275.
