Direct Simulation of the Full-Wave Partial Element Equivalent Circuit Using Standard SPICE [Application Notes]

The partial element equivalent circuit (PEEC) [1] is a computational electromagnetic (EM) method featuring circuit-oriented solutions for full-wave (FW) EM problems. An arbitrary threedimensional structure consisting of conductors and dielectric/magnetic materials can, after proper discretization, be transformed into an equivalent circuit composed of inductors, capacitors, and controlled sources that may be solved using a Simulation Program With Integrated Circuit Emphasis (SPICE)-like simulator or can be combined with external lumped circuits in a straightforward manner. Classical and recent applications of PEEC include interconnect modeling [2], [3], power integrity analysis [4], transient lightning modeling [5], transient electrostatic discharge simulation [6], power electronics [7], antenna analysis [8], [9], and modeling of magnetic materials [10]. Three very good and in-depth treatments of the subject can be found in [11][13].
