Title: Unidirectional transducer for lamb-wave delay lines
Abstract: A new type of unidirectional transducer is proposed and demonstrated. This transducer consists of three electrode groups, one on the bottom surface. The others are interdigital electrode groups 60° out of phase and on the top surface. Better than 20 dB of directionally was obtained for the zeroth symmetrical mode of a Lamb wave.
