Comparison of MoM implementations of surface impedance boundary conditions for material sheets with analytical and measurement data

In this paper, different types of surface impedance boundary conditions (SIBC) are implemented into the Method of Moments (MoM) to simulate arbitrary shape thin 3D material sheets in conjunction with other type geometry elements. These approaches are also extended to low frequency range using the loop-star approach. The developed approaches are validated by comparison of simulated results with those using analytical approaches and measurement data. Application of these approaches to automotive EMI problems will be demonstrated.
