Theoretical analysis of MUT using a simple 1D model

Micromachined ultrasonic transducer (MUT) structures are periodic, associating numerous elementary actuators excited in phase. Their simulation requires their operating conditions to be accounted for correctly. The development of an equivalent to the Mason model for MUTs would help in their promotion. We propose a simple model based on the material resistance theory to describe the flexural motion of a MUT. It is associated with the development of a periodic Green's function to simulate radiation in water.
