摘要： The invention concerns a component (B) operating with acoustic waves, in which the reflection and excitation are largely decoupled. For this purpose, a component comprises a dielectric (DL) which is arranged between an electrode finger (EF) and a piezoelectric substrate (PSU) and at least partially overlaps the electrode finger.

摘要： An electroacoustic transducer has reduced loss due to acoustic waves emitted in the transverse direction. For this purpose, a transducer comprises a central excitation area, inner edge areas flanking the central excitation area, outer edge areas flanking the inner edge areas, and areas of the busbar flanking the outer edge areas. The longitudinal speed of the areas can be set so that the excitation profile of a piston mode is obtained.
