Abstract :
In ultrasonics, a separation approach in connection with integral transform and point source synthesis is a powerful tool to calculate the transducer generated sound field in layered media with curved interfaces. The equations to calculate the displacement, the normal stress and the directivity patterns of the point sources are derived. Calculated sound fields are presented
