Surface-based PEEC formulation for modeling conductors and dielectrics in time and frequency domain combined circuit electromagnetic simulations

The Partial Element Equivalent Circuit (PEEC) formulation is an integral equation based approach for the solution of combined circuit and electromagnetic (EM) problems. In this paper, a surface-based PEEC formulation is presented as an alternative to the existing volume-based method. With the rise in the operating frequencies and the increasing complexity of test structures on boards, packages and chips, a surface based formulation is more efficient for many problems in terms of the number of unknowns generated. The composite conductor dielectric modeling is based on the PMCHWT formulation which is transformed into a PEEC representation using equivalent magnetic and electric circuits connected by mutual coupling. We are interested in both time and frequency domain analyses similar to a Spice type circuit solver. © 2004 IEEE.
