  • Abstract
    A ZnO piezoelectric film has been satisfactorily deposited on a concave substrate of a gold hemispherical shell to produce a concave transducer for microwave ultrasound. The fabrication process of the concave transducer, with a focal distance of 5¿9 mm, and also experiments on focusing radiation in water at 100 MHz. are described.
