Abstract :
The letter deals with radiation conductance of an interdigital transducer (IDT) for surface skimming bulk waves (SSBWs) on 41°- and 64°-rotated Y-cuts of LiNbO3. The radiation conductance was estimated theoretically by two methods and was compared with experimental results. The frequency response of SSBW IDTs on these cuts of LiNbO3 is similar to that of a conventional surface acoustic wave transducer, but markedly different from the response obtained when launching SSBWs from an IDT on rotated Y-cuts of quartz.
