An ultrasonic Gaussian transducer with a curved back electrode has been designed and fabricated. A theoretical principle of the design based on electromagnetic theory is developed. The experimental results show that the sound fields generated by the Gaussian transducers fabricated based on the design agree well with the theoretical predictions.
