Claim 31:
32. An acoustic wave device, comprising:
a plurality of piezoelectric layers having alternating parallel and antiparallel piezoelectric axis orientations, the plurality of piezoelectric layers having respective thicknesses, the respective thicknesses facilitating a main acoustic resonance frequency of the acoustic wave device in a Ka band;
a first metal acoustic wave reflector including at least a first plurality of metal electrode layers electrically and acoustically interfacing with a first piezoelectric layer of the plurality of piezoelectric layers; and
a second metal acoustic wave reflector including at least a second plurality of metal electrode layers electrically and acoustically interfacing with a second piezoelectric layer of the plurality of piezoelectric layers.
