Le 6 avril 2011, à 11h00, conjointement à l'Axe-1 de l'équipe RISC-E, l'équipe de Mécanique de l'Institut de Recherche Mathématiques de Rennes (IRMAR) invite William Parnell (School of Mathematics - University of Manchester) pour un séminaire Multiple scattering, a review, modern trends and some new thoughts Lieu : IRMAR, salle 6 bâtiment 22, campus de Beaulieu, UR1 Présentation : The classical theory of multiple scattering goes back many decades to the work of Foldy in 1945. Much progress has been made since then and there has been a renewed interest over the last decade. In this talk we will first discuss some historical results and compare the efficacy of these results with known solutions and bounding methods in specific parameter regimes. After this we will go on to discuss current work in the area, focusing on multiple scattering problems in a variety of application areas including waves on inhomogeneous strings, waves in acoustic ducts, flexural waves in heterogeneous thin plates and waves in pre-stressed nonlinear heterogeneous media.
