This work deals with the characterization of functional properties, including determination of mechanical and electrical losses, of piezoelectric materials using only one sample and one measurement. First, the natural resonant frequencies of a piezoe

International audience; The main principle of Resonant Ultrasound Spectroscopy (RUS) measurement method is to excite a sample and to deduce its elastic constants from its free mechanical resonant frequencies. The goal of this paper is to propose an a

In theoretically studying electromagnetic surface wave propagation in crystals possessing piezoelectric properties, we found that, if the frequency is smaller than typical phonon frequencies (not exceeding 1012–1013 Hz), then electric fields are ab

International audience; The success of cardiac surgery essentially depends on tissue preservation during intervention. Consequently a hypothermic cardio-plegia is applied in order to avoid ischemia. However, myocardial temperature is not monitored du

The ultrasonic air-coupled C-scan technique and X-ray radiography were used to detect impact damage in thin carbon fibre/epoxy composite plates. The sizes of damage zones were found in good agreement for both techniques employed. The presence of a po
