Integral Equations on Multi-Screens

by X. Claeys and R. Hiptmair

(Report number 2013-03)

Abstract
In the present article, we develop a new functional framework for the study of scalar wave scattering by objects, called multi-screens, that are arbitrary arrangements of thin panels of impenetrable materials. From a geometric point of view, multi-screens are a priori non-orientable non-Lipschitz surfaces. We use our new framework to study boundary integral formulations of the scattering by such objects.

Keywords: Scattering, trace spaces, junctions, boundary integral operators, boundary integral equations
