Abstract
A new type of transducer has been obtained for exciting only tangential displacement of a wave using an interdigital transducer. The device utilises a ferroelectric medium with a distributed polarisation caused by interdigital electrodes. An exciting interdigital electrode is located at the optimum position with respect to the polarisation pattern. Experimental results obtained with one such transducer are presented.
