Abstract
This paper describes the development of numerical model of a cMUT array element. The array is modeled in the same way than piezoelectric plates, i.e. using an equivalent linear matrix transfer. Radiation conditions of collective cMUT are discussed, in the baffle plane and far from the baffle. Finally, example of pulse is given and compared with experimental results
