Low-frequency expansions for a penetrable ellipsoidal scatterer in an elastic medium (EN)
Kiriaki, K (EN)
In this paper the scattering of a plane longitudinal or transverse wave by a penetrable ellipsoid in an isotropic and homogeneous elastic medium in the low-frequency region is examined. Using low-frequency expansions the scattering problem is reduced to a sequence of potential problems. Explicit closed-form solutions for the zeroth and first-order approximations are obtained. The solution of the problem was made possible by using an analytical technique based on Papkovich-Grodski-Neuber potentials. The normalized scattering amplitudes and the scattering cross-section are evaluated up to k3-order terms, respectively. © 1989 Kluwer Academic Publishers. (EN)
