Fecha de publicación: | feb-2004 | Editor: | Institute of Electrical and Electronics Engineers | Resumen: | This paper presents a computational method to calculate the reflected and transmitted ultrasonic fields at interfaces of complex geometry. The method is performed in two steps. As first step, the velocity potential impulse response from an arbitrary aperture is determined at the interface using the Rayleigh integral and considering the reflection and transmission coefficients. In a second step, the simulated fields are calculated by applying the Rayleigh-Sommerfeld integral to the whole, extended interface. In order to validate the method, some experimental cases as, for instance, plane and cylindrical concave surfaces between two media (water-acrylic) were tested. The experimental ultrasonic fields are in good agreement with those provided by the model. Furthermore, in the work, the compromise between the accuracy of the method and the computation time is studied. | Versión del editor: | http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1320766 | URI: | http://hdl.handle.net/10261/8222 | ISSN: | 0885-3010 |
