Multidomain ferroelectric vibrator. (1) plate, (2) metal electrodes, (3) pickup electrode to read an electric potential, (4) stage.
Distribution of an electric potential along two adjacent inversely poled domains. Plot 1—calculation by Eq. (1); plot 2—result of FEM computation; plot 3(circles)—experimental data from the sample LTa3 at domain resonance frequency of 2.947 MHz; plot 4 represents an electric potential distribution in a non-piezoelectric media .
Admittance vs frequency. Plot 1 (circles)—experimental data from the sample LT4a3; plot 2—FEM calculation for a single domain vibrator, no domain resonance is observed; plot 3—FEM computation for two-dimensional periodically-poled vibrator with .
