Abstract :
For ultrasonic problems, an optimized approximation method was developed to calculate the transducer generated sound field in layered media with curved interfaces. The transient sound field is calculated for two-layered problems such as angle beam probes coupled to a half-space, and sound fields in steel after a water delay. It is demonstrated that Snell´s law is not applicable to calculate the incidence angle of the sound field generated by a limited element
