Paper Abstract
This paper presents the simulation of various electromechanical performance parameters for an efficient and broadband
air coupled Capacitive Micromachined Ultrasonic Transducer (CMUT) for Non Destructive Testing and Evaluation
(NDT/NDE) using FEM simulation tool, Coventor Ware. The non contact ultrasonic inspection performed in ambient air
reduces the complexity and cost. Various critical parameters like collapse voltage, resonant frequency, coupling
coefficient, squeeze film damping, bandwidth, quality factor and transient response of the single cell of CMUT are
discussed. We employ a hexagonal CMUT cell for the modeling to improve the CMUT’s transmission/reception
efficiency as the average membrane displacement is high.
