Design, fabrication and operation of a very high intensity CMUT transmit array for beam steering applications

Khan, Talha Masood (Bilkent University, 2020-12)

Several studies have reported airborne ultrasound transmission systems focused on achieving beamforming. However, beam steering and beamforming for capacitive micromachined ultrasonic transducers (CMUTs) at high intensity ...
High-Intensity airborne CMUT transmitter array with beam steering

Khan, Talha Masood; Taşdelen, Akif Sinan; Yılmaz, Mehmet; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2020)

A 2×2 high-intensity CMUT transmit array that is capable of two-dimensional beam steering is presented. The device uses an ac drive voltage at half the ultrasound frequency without any dc bias, enabling the usage of the ...
