  • Wide-band ultrasonic transducer and its uses
    Patent number: 3968680
    Abstract: A wide-band ultrasonic transducer comprising: a body of revolution; at least two electrodes connected to the body of revolution; the body of revolution being made of a material having piezoelectric properties; the body of revolution having one flat end face surface, whereas its other end face surface, opposite to the flat end face surface, is profiled. The profile of the profiled end face surface of the body of revolution is made in accordance with the following relationship:h'= -.rho..sup.. h.sup.. k(f)Where.rho. is the radial coordinate; radialh is the thickness of the transducer, corresponding to the radical coordinate;k(f) is the frequency characteristic of the transducer within the operating frequency range; andh' is the derivative of the transducer thickness with respect to the radial coordinate.The electrodes are applied onto the flat end face surface and the profiled end face surface of the body of revolution.
