A capacitive micromachined ultrasonic transducer(cMUT) based on fluid-solid coupling modelis developed by ANSYS.The acoustic characteristics of cMUT array in different medium is researched.The effect of membrane dimensions
cavity thickness
and distance change of sensor unit on transmission of sound pressure and bandwidth is also investigated.Simulation experiment results indicate that bandwidth can be increased by increasing membrane radius
decreasing gap thickness and distance of sensor unit.
