This translates to the stiffening of the transducer and increases the acoustic velocity, which results in a higher resonance frequency. Here, the local polarization switching concept is demonstrated using a 97 MHz laminated ferroelectric Sc <inf xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>0.28</inf> Al <inf xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>0</inf> . <inf xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>72</inf> N resonator operating in its 3 <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>rd</sup> width-extensional mode, with a Q of 687 and a k <inf xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>t</inf> <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> of 2.26%. A frequency tuning of 0.65% is achieved, without any degradation in Q, through application of fifteen ~78.5V monopolar pulses with a frequency of 20kHz. This tuning range exceeds the overall 0.53% temperature-induced frequency drift in the resonator over -40°C to 80°C range.
