摘要：

A unidirectional device for acoustic focusing has been devised. The transducer consists of a group of three electrodes deposited on two surfaces of a thin piezoelectric ceramic plate. One of them is used as a common earth electrode and is on the substrate surface in contact with water. The others are interdigital electrodes on the other surface. The design and basic focusing properties of the device are described. © 1979, American Association of Physics Teachers. All rights reserved.
