ABSTRACT:
A component working with guided bulk acoustic waves includes a first substrate, a second substrate, and a layer system between the first and second substrates. The layer system includes a metal layer and a dielectric layer. A ratio of the acoustic impedance of the metal layer to the acoustic impedance of the dielectric layer is greater than or equal to 4.5.
