The time domain analysis is an interesting alternative to spectral domain computations for vibrating structures or wave-guides exhibiting short impulse responses. we propose a development allowing for solving periodic transient problems. As for harmonic computations, we mesh only one period of the array and we then apply boundary conditions relating its(More)
In this work, we report on the design and test of a cMUT structure based on a thin silicon membrane shaped in order to comply our modeling assumptions, i.e. long 2D-like cMUT cells able to operate conformably to the simulated operation of an actual 2D structure. The device is designed to operate at a minimum of 6 MHz in air and to exhibit an operation(More)
Micro-machined Ultrasonic Transducer (MUT) structures are periodic, associating numerous elementary actuators. These transducers can be accurately analysed or even designed using mixed finite element analysis/boundary element methods (FEA/BEM). In this work, we report on the design and test of a cMUT structure based on a thin silicon membrane shaped in(More)
