Junction modeling for piecewise non-homogeneous geometries involving arbitrary materials

This paper presents a new method for the electromagnetic analysis of metallic and/or dielectric structures that are in contact with other metallic and/or dielectric structures. The method is based on modeling each junction edge by sets of fictitious ordinary Rao-Wilton-Glisson (RWG) functions. Unlik...

Summary:This paper presents a new method for the electromagnetic analysis of metallic and/or dielectric structures that are in contact with other metallic and/or dielectric structures. The method is based on modeling each junction edge by sets of fictitious ordinary Rao-Wilton-Glisson (RWG) functions. Unlike other approaches, the proposed method can be easily implemented in existing MoM (Method of Moments) codes, capable of handling open and/or closed, disconnected, metallic and/or dielectric bodies. This is because the boundary conditions at junction edges are imposed to the MoM matrix after it has been generated by the existing MoM method. Additionally, the presented junction method is applicable to any Surface Integral Equation (SIE) formulation. A simulation example is analyzed in order to assess the accuracy and iterative performance of several MoM implementations based on different SIE formulations.
