摘要：
The characteristics of air-coupled ultrasonic capacitance transducers have been determined for a of transducer configurations. The pressure field of a wide bandwidth silicon backplate capacitance transducer has been scanned in air, and compared to theory based on a plane piston approach. New devices have been fabricated, using laser-machined backplates. The devices have also been used in an air-coupled tomographic imaging experiment.
