Acoustical tuning of CMUT receiver arrays
(IEEE, 2016)Cell placement in an element and structural modifications on the array baffle significantly change the bandwidth, band shape and signal to noise ratio of a CMUT receiver array. In this paper, optimum receiver performance ... -
Batch-compatible micromanufacturing of a CMUT array for optoacoustic imaging of tissue-like phantoms
(Bilkent University, 2021-08)Photoacoustic imaging (PAI), also named optoacoustic imaging, is a technol-ogy for medical imaging that relies on contrast data due to optical stimulation. Capacitive micromachined ultrasound transducers (CMUTs) are ... -
Design, fabrication and operation of a very high intensity CMUT transmit array for beam steering applications
(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 ... -
Designing, fabrication and post- fabrication characterization of half-frequency driven 16 x 16 waterborne transmit CMUT array
(Bilkent University, 2021-02)Capacitive Micromachined Ultrasonic Transducers (CMUT) are micro-scaled electromechanical devices which are used to either transmit or receive pressure signals and applicable for various purposes such as ultrasonic sensor, ... -
Electrically unbiased and half frequency driven waterborne 16×16-element 2-D phased array CMUT
(Bilkent University, 2019-08)Capacitive micromachined ultrasonic transducers (CMUT) are typically used as arrays consisting of separate cells or interconnected sub arrays, and these cells have several operation modes. Design procedure and ... -
High Power CMUTs: design and experimental verification
(IEEE, 2012)Capacitive micromachined ultrasonic transducers (CMUTs) have great potential to compete with piezoelectric transducers in high-power applications. As the output pressures increase, nonlinearity of CMUT must be reconsidered and ... -
Transmitting CMUT arrays without a DC bias
(IEEE Computer Society, 2019)This study focuses on design, simulation, fabrication and measurement of transmitting CMUT arrays with unbiased mode of operation. We presented a design procedure considering the radiation pattern, Rayleigh distance and ... -
A triple-band antenna array for next-generation wireless and satellite-based applications
(Cambridge University Press, 2016)In this paper, a triple-band 1 × 2 and 1 × 4 microstrip patch antenna array for next-generation wireless and satellite-based applications are presented. The targeted frequency bands are 3.6, 5.2 and 6.7 GHz, respectively. ...
