Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers
(IEEE, Piscataway, NJ, United States, 1998)
The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ...
Circuit theoretical method for efficient finite element analysis of acoustical problems
In the last decade, there has been an outstanding improvement in the computer aided design tools for VLSI circuits regarding solution times and the circuit complexity. This study proposes formulating the acoustic field ...
A new approach to holographic video imaging: principles and simulations
As the importance of 3-dimensional information displays in many fields increases, more attention is given to holographic displays. Different kinds of holographic displays are reported in the literature, but the resolution ...
Silicon micromachined ultrasonic immersion transducers
(A I P Publishing LLC, 1996-12-09)
Broadband transmission of ultrasound in water using capacitive, micromachined transducers is reported. Transmission experiments using the same pair of devices at 4, 6, and 8 MHz with a signal‐to‐noise ratio greater than ...
A synthetic aperture imaging system using surface wave modes
A synthetic aperture acoustic imaging system with a novel inversion algorithm is described. Data is obtained by using a transducer insonifying the sample surface at a critical angle which is excited by a short electrical ...
