ABSTRACT:
An interdigital transducer used in an elastic surface wave device and including a pair of electrodes each having a common electrode and a plurality of electrode fingers connected to the common electrode, the overlap lengths of electrode fingers being uniform throughout the transducer. Floating electrodes, each having two parallel conductors connected together at one end, are disposed between the interdigital electrode fingers of the paired electrodes to weight the excitation electric field strength.
