Influence of Absorption on Non-Specular Ultrasonic Reflectivity

Influence of Absorption on Non-Specular Ultrasonic Reflectivity

A numerical integration method is developed for calculating the changes in beam profile and amplitude upon reflection of a bounded ultrasonic beam incident on a liquid-solid flat interface at the longitudinal wave critical angle and the Rayleigh angle. No approximations, valid only at the Rayleigh a...

Zusammenfassung:A numerical integration method is developed for calculating the changes in beam profile and amplitude upon reflection of a bounded ultrasonic beam incident on a liquid-solid flat interface at the longitudinal wave critical angle and the Rayleigh angle. No approximations, valid only at the Rayleigh angle, are used, and the method is applicable to all angles of incidence. (Author)
