An acoustic lens design using the geometrical theory of diffraction

The design of an acoustic lens that reduces the diffraction spreading from an ultrasonic transducer to produce a narrow focused beam is proposed. The design is based upon a description of the radiated field using the geometrical theory of diffraction.
