  • Surface wave transducer, especially of split finger design, with suppression of reflections of terminal transducer fingers
    Patent number: 5304965
    Abstract: A surface wave transducer has measures for suppressing internal reflections on terminal fingers of a transducer having other transducer fingers, which are arranged interdigitally adjacent to the terminal fingers, which are arranged corresponding to a specified acoustic wavelength of the transducer at intervals specified by a predetermined scheme and which are designed with finger widths that are likewise specified by the predetermined scheme. On each end of the transducer only a plurality of terminal fingers, which are connected to one busbar of the transducer, are positioned deviating from the scheme for positionings and finger widths of the other transducer fingers and are positioned deviating in their finger strip width.
