摘要：
Normal-mode expansions for Green's functions are derived for ocean-bottom systems. The bottom is modeled by Kirchhoff and Reissner-Mindlin plate theories for elastic and poroelastic materials. The resulting eigenvalue problems for the modal parameters are investigated. Normal modes are calculated by Hankel transformation of the underlying equations. Finally, the relation to the inverse problem is outlined.
