title = "Method for measuring the intensity of ultrasonic radiation in solid medium",
abstract = "A method based on stratified measurement and inverse fitting is proposed to measure and analyze the intensity of power in solid medium aiming at the problem of power ultrasonic intensity measurement in solid. The thickness of the typical solid medium is determined according to the sound pressure distribution on the acoustic axis of the simulated sound field, and the surface acoustic field is measured separately to obtain the change of the sound intensity in the radial direction. Then the measurements of different thicknesses are fitted based on a fractional linear fit algorithm. Finally, the distribution of the power ultrasonic field in the solid is obtained by using the fitting equation. This paper also compares the experimental measurement results with the COMSOL simulation results. The two have a high degree of similarity in the trend of change, indicating that the measurement scheme is feasible.",
