Claim 13:
14. A method for signal processing, comprising:
receiving a signal at a terminal of an electroacoustic device; and
processing the signal via the electroacoustic device, wherein the electroacoustic device comprises:
a substrate;
a bottom electrode layer disposed above the substrate;
an acoustic mirror stack having:
a first dielectric layer disposed above the bottom electrode layer; and
a first conductive layer disposed above the first dielectric layer;

a piezoelectric layer disposed above the acoustic mirror stack; and
one or more first vias disposed between the bottom electrode layer and the first conductive layer, the one or more first vias electrically coupling the bottom electrode layer and the first conductive layer.
