- 論文の詳細を見る
In this paper, we carried out equivalent circuit analysis for a multilayered transducer including the backing and load effects. The calculated resonance frequencies showed good agreement with previously measured values. The improved multilayered transducers in this study exhibit good characteristics for output sound pressure when loaded with water. We also demonstrated designs for a four-layer polyurea transducer with a frequency of up to 220 MHz. As a result, designs for a wide frequency range can be obtained by varying the polyurea thickness.
