1. An acoustic wave device comprising:
a piezoelectric layer; and
an interdigital transducer electrode on the piezoelectric layer, the interdigital transducer electrode including a bent section arranged to create a curvature in an acoustic aperture of the acoustic wave device to suppress a transverse mode of the acoustic wave device, and the acoustic aperture having substantially the same width throughout the bent section.
