Bulk Acoustic Wave Transformer employing Periodically Polled array of Piezoelectric Rods
Paper in proceeding, 2016

Multilayer bulk acoustic wave transformer employing a periodical array of piezoelectric rods with alternating polarization is experimentally demonstrated for the first time. Voltage transformation coefficient in excess of 6 was measured at a frequency of 150kHz, providing thus a solid experimental verification of the recently proposed principle of operation. Finite element analysis is used to reveal the underlying device physics.
