In non destructive testing and more recently in medical applications ultrasonic transducers have been used for emitting or receiving brief signals. It is specially important that these signals must decrease rapidly enough to avoid masking of weak echoes behind strong ones. For this reason diffraction effects on focused transient radiation have been the object of numerous studies in the past years. Although the impulse diffraction theory seems to be mastered now, the characteristics of the transducers remain very important and constitute very often the main limiting features of the spatial axial or longitudinal resolution achieved from either single transducers or arrays.
