Stability Improvements of Integral Equation Models

The Partial Element Equivalent Circuit (PEEC) technique is a circuit based formulation which is numerically equivalent to a full wave method of moments solution with Galerkin matching. In this paper, the PEEC formulation is used to illustrate how the high frequency model behavior can be improved for integral equation formulations. These improvements are important for both model reduction and time domain applications. The effectiveness of the method is illustrated with an example, and our results are compared with a conventional Method of Moments (MOM) code.
