Dual-electrode CMUT with non-uniform membranes for high electromechanical coupling coefficient and high bandwidth operation
In this paper, we report measurement results on dual-electrode CMUT demonstrating electromechanical coupling coefficient (k(2)) of 0.82 at 90% of collapse voltage as well as 136% 3 dB one-way fractional bandwidth at the transducer surface around the design frequency of 8 MHz. These results are withi...
