Claim 26:
27. An acoustic wave device comprising:
a substrate;
a first piezoelectric layer having a first piezoelectric axis orientation;
a second piezoelectric layer acoustically coupled to the first piezoelectric layer, the second piezoelectric layer having a second piezoelectric axis orientation that is antiparallel to the first piezoelectric axis orientation;
a first metal acoustic wave reflector including at least a first quadruplet of metal electrode layers electrically and acoustically coupled with the second piezoelectric layer; and
a second metal acoustic wave reflector including at least a second quadruplet of metal electrode layers electrically and acoustically coupled with the second piezoelectric layer, in which the acoustic wave device has a main resonant frequency that is in a Ku band.
