Abstract

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.
