Method of Moments Modeling of Backscattering By a Soft–Hard Strip

Method of moments (MoM) is applied in modeling and simulation for backscattering from a strip with one face soft and the other face hard (i.e., with Dirichlet and Neumann boundary conditions, respectively). The results are compared with high-frequency asymptotics (HFA), such as physical theory of diffraction (PTD) and theory of edge diffraction (TED) approximations.
