Circuit Oriented Electromagnetic Modeling Using the PEEC Techniques

Chapter 8Geometrical Description and Meshing

In this chapter, we present an overview of issues for the meshing for partial element equivalent circuit (PEEC) models. We specifically consider applications in the electromagnetic modeling (EMM), electromagnetic compatibility (EMC) areas such as interconnect modeling for power and signal integrity (SI) as well as power engineering area models. Hence, these structures include different complex mixed circuit and electromagnetic (EM) aspects. The EM structures are in general very heterogeneous and they may be connected to electronic circuits that are described in the circuit domain.

Early on in the history of PEEC models, simplified nonorthogonal geometries were modeled in terms of rectangular bars [1–4]. While the use of rectangular bars is very efficient, it also limits the geometries that can be represented with these shapes. Hence, the consistent inclusion of nonorthogonal shapes with the rectangular ones is important and evolving. In general, we need to consider a multitude of shapes for the applications of interest. Rectangular blocks are used for some parts such as printed circuit boards (PCBs) and transmission line conductors. Different round conductors are used for connection wire models of different shapes. Very thin conductors are modeled with lines or quadrilateral cells or other approximations, and volumes are represented with hexahedral models and if possible rectangular block shapes.
