In order to bring about a reduction in the reflection coefficient due to reflections on the successive fingers of a transducer in the form of interdigitated transducer elements with split fingers of unequal length when a load impedance is applied at the terminals thereof, the invention provides for the displacement of at least the smallest minor lobe of the pulse response envelope, whose design is reproduced by the fingers, in order to position it in front of one of the maxima of the major lobe. |
