ABSTRACT:
A wide band surface wave transducer is provided with means for launching a surface acoustic wave on a non-piezoelectric material by first launching the surface wave at the surface of a piezoelectric material spaced apart from the aligned non-piezoelectric element. A mechanical coupling array provides energy transfer between the two wave propagating surfaces.
