Scattering Under Linear Non Self-Adjoint Operators: Case of In-Plane Elastic Waves
In this paper, we consider the problem of the scattering of in-plane waves at an interface between a homogeneous medium and a metamaterial.The relevant eigenmodes in the two regions are calculated by solving a recently described non self-adjoint eigenvalue problem particularly suited to scattering studies.The method efficiently produces all propagating …
