摘要：

The finite element method is firstly used to simulate the laser-induced leaky waves at fluid-solid interfaces. Corresponding models and arithmetic are developed, in that the fluid-solid interactions are described by a coupling matrix and the infinite boundary of fluid domain is modeled by acoustic absorption elements. Typical calculations are executed for air-aluminum plane and cylindrical interfaces. The results are in very good agreements with the experimental signals in available literatures, which verify the correctness of our finite element model for simulating laser-induced leaky wave at fluid-solid interfaces. And some elementary conclusions are obtained for the laser induced leaky waves. (C) 2007 Elsevier B.V. All rights reserved.
