초록
Finite element models are constructed using the commercial code ANSYS for two most representative types of ultrasonic transducers, cMUTs and piezoelectric transducers. Calculation result shows the origin and level of cross talk between array elements in each transducer type For reduction of the cross talk level, the effects of various structural variations are Investigated for each transducer type. The results say that proper design of the coupling isolation structures between the transducing elements can significantly reduce the cross talk in ultrasonic transducers.
