    摘要: The invention relates to an electroacoustic transducer for a component operating with surface waves, comprising two electrodes having alternately arranged fingers and stub fingers, each connected to a bus bar, the opposing fingers and stub fingers being separated from one another by gaps. In this case, the position of the gaps in the transverse direction preferably has a periodic variation. The pattern of the variation in the gap positions, which, in particular, influences the excitation intensity of the acoustic wave in the edge region of the transducer, is selected so that the excitation profile of the acoustic wave is adjusted to the predetermined energy density profile. As a result of such an adjustment, it is possible to significantly reduce signal losses at the resonant frequency.
