Abstract:
1. An ultrasonic plane wave generator comprising: a first sheet of piezoelectric material and a second sheet of piezoelectric material; a shared electrode between the first sheet and the second sheet; a first electrode set having a plurality of electrodes positioned with respect to the first sheet to form a first ultrasonic plane wave generator set, wherein an ultrasonic plane wave generator in the first ultrasonic plane wave generator set includes the shared electrode, the first sheet, and one of the electrodes in the first electrode set; and a second electrode set having a plurality of electrodes positioned with respect to the second sheet to form a second ultrasonic plane wave generator set, wherein an ultrasonic plane wave generator in the second ultrasonic plane wave generator set includes the shared electrode, the second sheet, and one of the electrodes in the second electrode set.
