Abstract
An ultrasound transducer assembly includes a housing; a wedge-shaped acoustic modal convertor (AMC) in the housing with a first surface exposed by an opening in the housing, and a second surface that meets the first surface at a tip located in the housing, and extends from the tip at an angle into the housing, wherein the second surface has a recessed portion formed therein, wherein the second surface of the AMC is oriented at a specific oblique angle to the first surface of the AMC; and a piezoelectric ultrasound transducer disposed in the recessed portion of the second surface of the AMC, wherein the piezoelectric ultrasound transducer is connected to an electrically tuned circuit that resonates at a specific frequency and has a finite bandwidth.
