Electromagnetic Compatibility for High-Speed Circuits
Published in Xing-Chang Wei, Modeling and Design of Electromagnetic Compatibility for High-Speed Printed Circuit Boards and Packaging, 2017
Partial element equivalent circuit (PEEC) is a typical field–circuit hybrid method. For the PEEC method, usually the electromagnetic field integral equation is solved to extract the partial inductance, resistance, and capacitance of the structure, so the problem will be transferred from the electromagnetic domain to the circuit domain, where conventional simulation program with integrated circuit emphasis (SPICE)-like circuit simulators can be employed to analyze the equivalent circuit. There are several advantages of the PEEC method over the full-wave methods, such as one can easily integrate any electrical component (RLCG components, sources, non-linear elements, ground, etc.) into the PEEC circuit. At the same time, using the PEEC circuit, it is easy to exclude capacitive, inductive, or resistive effects from the model, when it is possible, in order to make the model smaller. For example, in the power electronics application, where the magnetic field is a dominating factor over the electric field, the PEEC circuit can be simplified by just neglecting all capacitance in the model.

The partial-element equivalent circuit method (PEEC) was belong to hybrid method, which was a combination of the mixed-circuit method and the electromagnetic-field method and boasts the advantages of both. The PEEC was developed to simulate the lightning response of the grounding grid in [28, 29]. However, it is considered to represent only half of the homogeneous earth model.
