ABSTRACT:
Transducers are connected in parallel on a piezoelectric substrate. Each of the transducers is constituted of RSPUDTs. The RSPUDTs include SPUDTs that are opposed to each other such that their propagation directions are opposite to each other. The SPUDTs have a unidirectional electrode structure having a propagation characteristic.
