A Lamb wave device for a communication system with ternary logic

A new type of Lamb wave device for signal processing with ternary logic is presented. The transducer consists of a group of three electrodes deposited on two surfaces of a thin piezoelectric substrate. One is on the bottom surface as a common earth electrode. The other two are interdigital electrodes on the top surface. By using the device having two transducers, a communication system with ternary logic is demonstrated.
