Abstract
An ultrasonic transducer includes a backing element, an active element overlying the backing layer, and a matching element overlying the active element, the matching element having an inner surface that contacts the active element and an outer surface with a non-homogeneous texture and/or material composition. The matching element may be formed by subtractive or deposition techniques.
