“…Reasons for PEEC model time-domain instabilities are 1) delays in full-wave formulations; 2) properties of some explicit and implicit numerical timedomain integration technique [8], [15], [16]; 3) poor meshing of geometry (which is also related to the delay discretization for full-wave models, e.g., [17]). These issues have been treated in the literature and solutions have been proposed to improve the stability of PEEC models based on these analyses.…”

Abstract-Electromagnetic solvers based on the partial element equivalent circuit (PEEC) approach have proven to be well suited for the solution of combined circuit and EM problems. The inclusion of all types of Spice circuit elements is possible. Due to this, the approach has been used in many different tools. Most of these solvers have been based on a rectangular or Manhattan representation of the geometries. In this paper, we systematically extend the PEEC formulation to nonorthogonal geometries since many practical EM problems require a more general formulation. Importantly, the model given in this paper is consistent with the classical PEEC model for rectangular geometries. Some examples illustrating the application of the approach are given for both the time and frequency domain.Index Terms-Circuit modeling, partial element equivalent circuit (PEEC) method , full-wave analysis.

“…In the classical implementation of the PEEC method, coarse approximation of the delays in the resultant delay differential equation (DDE) were used which impact both stability and accuracy. The time domain stability of integral equation based techniques has been a research topic for many years [3] since they result in a fast solution approach. Stability improvements also imply improvements in passivity since stability is a necessary condition for passivity.…”

Abstract-It is well known that time domain integral equation techniques may suffer from stability problems and frequency domain models may provide non-passive results. A main source of these issues is the delay of the coupled elements. In the classical Partial Element Equivalent Circuit (PEEC) method, a single delay was used for each couple of partial element which results in a delay differential equation with reduced stability and accuracy. In this paper, we consider multiple delay coefficients which can be used for both the time and frequency domain. Also, filters are introduced which remove unwanted eigenvalues or resonances in the partial element couplings. This can substantially improve the response of the frequency domain and the time domain models. Stability improvements also means passivity improvements.
