| Abstract | High frequency ultrasonic wave propagation in an porous aluminium sheet is modelled and the results by experiment using focused broadband 50, 100 and 175 waves. For colinear (pores extending from face to face of sheet) samples the microstructure facilitates transmission at beyond 35°, which is far greater than the critical angles a homogeneous solid, and at a constant velocity. ©2008 IEEE. |
