摘要:
An improved electroacoustic transducer with an improved mode profile is provided. The transducer comprises a transversal velocity profile with a periodic structure and an edge structure flanking the periodic structure. The velocity profile also allows to suppress the SH wave mode. A dielectric material with a periodic structure contributes to the formation of the periodic structure of the velocity profile.
