위상배열된 마이크로폰에서 압전세라믹이 여러층으로 적층되어 사용된다. 여기에선 한 층으로 된 압전 트랜스듀서를 해석하여 음압과 전압에 의한 변형을 계산하고자 하였다.

In a phased-array microphone, the piezoelectric crystal plate fits into the structure through a series of stacked layers, which are divided into rows. The space between these layers is referred to as the kerf and the rows are repeated with a periodicity, or pitch. Using functionality provided by the Acoustics Module, this example simulates a single row of such a structure, solving for the acoustic pressure generated by the transducer and the structural deformation due to the electric load.
