Multi-material additive manufacturing is receiving increasing attention in the field of
acoustics, in particular towards the design of micro-architectured periodic media used to …

In this paper we are interested in the acoustic scattering by plane periodic media immersed
in a fluid. In particular, the effects of viscosity on the stop and pass bands are investigated …

The study of the ultrasonic acoustic response of materials is of increasing interest for the
characterisation of high-frequency applications. In this work, some elastic properties …

The paper deals with the study of the resonances of 1D periodic media composed of N
elementary cells formed with two perfectly bonded layers which exhibit a high acoustic …

In this research, the influence of the insertion of two geometric defect layers in a 1D
Phononic crystal composed of N elementary cells is investigated by analyzing the band …

Solidly mounted resonators (SMRs) with an acoustic Bragg reflector should be more suitable
for high power RF filters than a self-standing structure because heat can be transferred to …

This work deals with the study of the reflection and transmission properties of plane periodic
structures composed of N periods (1≤ N≤ 3) in the MHz frequency range. The period …

During the Resin Transfer Molding (RTM) process, bubbles can appear and move between
fiber strands and fiber folds. In this study, a monitoring method for the size and velocity of air …

Obviously, the resulting infinite summation has to be reduced to a finite one, according to
some level of accuracy. The numerical estimation of the transmission coefficient using the …

We are interested in a medium composed of N periods including two perfectly bonded plates
which exhibit a high acoustic impedance contrast. N is varied from 2 to 10. Among the …
