Abstract

The PEEC method and solvers are continuously evolving as more new features are added to the approach. Finite dielectrics were added to solve a new class of multi dielectric problem. Dielectric losses are becoming more important with the recent increase in the frequencies in the problems which need solving. In this work, we provide an approach which is applied to the dielectric model to include losses. Recursive convolution and circuit synthesis techniques are employed to take into account the dispersive behavior of the dielectric. Presently, the algorithm has been applied to materials with a Lorentzian model for the complex permittivity. The accuracy of the proposed approach is demonstrated by an example
