Abstract :
A surface wave transducer is described which radiates acoustic power in essentially one direction. Using Y cut, Z axis propagating lithium niobate and unidirectional transducers, a delay line has been constructed that exhibits 6.5-dB insertion loss and 52-dB triple-transit echo suppression at 106.5 MHz.
