Abstract
An acoustic well-logging transmitting transducer employing a transmitter portion comprising stacked piezoceramic rings and a resonating metallic plate, the dimension of which determines the frequency, and a conical acoustic reflector for causing reflections to impinge omnidirectionally on the wall of the borehole at an angle to enhance shear wave component propagation. A receiving portion of similar construction can also be employed.
